CBSE Class 9 Science Examination - Preparation Tips

The NCERT Solutions for Science Class 9 contains all the important questions that are available in the NCERT textbook. Most of the questions available in this book can be expected to come in the annual examination. Hence, students should solve all the questions available in the NCERT Solutions book thoroughly in order for them to prepare for their examinations. The solutions provided by Vedantu will help students to ace their examinations with confidence as all the answers are provided in a step by step manner. Once students are able to understand how to answer certain questions and problems, they will be able to answer all the complex and twisted questions in the question paper without any difficulty.

You should go through the NCERT Solutions of Science Class 9 as it will help you to write answers in a concise and precise manner. Going through these chapter-wise solutions will improve your understanding of the concepts and will also boost your confidence, keeping you ready ahead of the crucial CBSE Class 9 Science examination. There are several techniques explained here that you can use for preparing well in Science.

You can always carry a little diary or notebook where you can jot down the crucial formulas/ principles or definitions to be used for particular sections. Note down a few terms and diagrams illustrating the experiments, explaining the important principles. You may also use it for last-minute revision. You need to have a thorough understanding of all the concepts rather than going through each and every word of the text and trying to remember the same. Resolve your doubts, if any, by attending the live classes at Vedantu without any hassles.

You must prepare a study plan as well if you want to do well in your exams. This way you will be able to space out your time and you will understand what topics and concepts you must focus on more. While creating your study plan you must make sure that you give time to yourself to breathe and take some rest. If you sit to study for hours you may get tired easily and your brain won’t be able to retain a lot of information altogether. You should also make sure that you take care of yourself during your examination. You must eat healthy and get sufficient sleep during your exams.

One of the best ways to prepare for your exams would be to practice. You must practice as much as you can. You can solve previous year’s papers, sample papers, and other question banks. This will help you get an idea of the exam pattern and the type of questions that can be asked. You must solve previous year’s question papers which are at least 10 years old. Apart from understanding the question and question paper pattern, you will even be able to manage your time properly. Time management is very important when it comes to writing an exam. You must know which section to pay more attention to and which section you will be able to finish quickly. Practicing with sample papers and other question banks will help you to manage your time accordingly.

Do not make a habit of procrastinating and allow your mind sufficient time to get a grasp of new concepts.  Start your preparation early and spare the last few days for exams. Prior to the exams, make sure you have covered all the topics beforehand. Learning new things just before the exams will not be favourable. Also, if you get study leaves before your exams then utilize those days carefully. Make a timetable and chalk out your subjects. Science subjects need more time to practice so allot at least 2-3 hours in a day for Science. Practice the numericals in the first hour and then spend another hour on revision and reading. You should also solve a few questions every day. Try to sit to study as early in the morning as possible when your mind is fresh. This is the time when your mind is the most active. If you have someone at home to help you out with studies, ask him/her to sit with you and check your answers when you solve them. Go through the corrections yourself to know where you went wrong. If you do not have anyone to help you out, try to do it yourself.

You should also understand that referring to NCERT Solutions for Class 9 Science is considered to be sufficient to prepare for your examinations. These solutions are framed by Vedantu keeping in mind the abilities of students. These solutions are provided in detail to help you easily understand all the complex topics and concepts. You can even learn technique and tricks to understand the topics better. In order for you to get an overall idea of the concepts, you must start to prepare for your exam beforehand.

Some Other Vital Suggestions for Studying

Another suggestion to study better is to have group studies. However, for this purpose, you and your group have to be really serious and dedicated. When you study in groups, you help each other to understand topics better. When you try to explain something to your friend, your own concepts are clarified better. This way both you and your friend benefit from a group study session. This is something you should always keep in mind since you have to ensure full utilization of these sessions. This is a good habit to have, particularly before the examinations.

Make a habit of solving question papers from the previous year. This will help you to get a hold of the different topics and question patterns usually followed in the exam. In case you do not have the previous years’ question papers, then get hold of some mock test question papers or sample test papers. Solving them is beneficial as you will be fully prepared with the format. Having a set of formulas ready for revision helps you with solving the sums. When you are revising through chapters that require you to do sums, have a separate notebook for writing down the formula. This book is of great help for last moment revision. You will not have to go through page after page looking for the formulas. All you need to do is open the notebook and check the formulas you need. This will help you stay abreast of the important formulas without having to really fret about finding them all over again in case you forget. A common scenario isn’t it? Well, a little strategy will help you overcome these hurdles with ease.

If you are a student who has problems with maths, you will need to practice a bit more than the others. Your theory should be well-prepared so that you can score better in that part. If you have the fear of mathematics, then make it a point to overcome that fear. Do not worry! Maths is not that difficult! All you have to do is forget the difficulty and practice daily. That is the only mantra behind acing maths. Just wake up in the morning and practice 2-3 sums from each chapter. Read the questions carefully before attempting the problem. Understand what it wants and what is already given. Go ahead with it when you understand the question properly.

One more important tip before exams that one must follow is being less distracted. You may think your guardian is being absolutely ruthless when he/she asks you not to watch TV before exams. But what he/she means is that you should wisely utilize your time and distract your mind. It is very important to get into that mindset of studying before exams. Try not getting disturbed or distracted as your mind needs to be in the right state to help you prepare. Allot a specific time for activities such as watching TV or playing video games. Make a time table for that too. You can study the whole day and have a recess period of 2 hours after studying, preferably at night before you go to bed.

Before you write your exam you must make sure that you do a complete revision at least 3 times. Make sure that you don’t learn any new topics one night before the exam. This will only lead to confusion and you might even forget the other topics and concepts that you learned. You should revise one day before the exam, during the night, and then you can do a quick revision in the morning. With the notes that you have, revising concepts and topics will make it easier for you to do. For Class 9 Science , it is important for you to revise how to draw all the diagrams that are required for the examination. This will help you score better marks.

What Else Should You Know While Preparing?

Eating and sleeping sufficiently before exams are very necessary for your body. Eat your food on time and sleep on time. Do not compromise on sleep or go to bed late just the night before your exam. This can cause severe headaches in the morning, potentially making you fall sick while writing your exam. Take proper food with a balanced diet plan so that both your body and mind are healthy.

Lastly, do not take too much pressure. If you are having a problem with any chapter, just get help from Vedantu. Do not stress too much and take short breaks in between study hours. Sitting for long periods can give you back pain and stress you out. Start with the difficult chapters first and then move on to the chapters you find easy. Keep your notes and books arranged so that you do not have to get up repeatedly. Keep cell phones and video games away from the study table. Anything that distracts you should remain out of your sight.

On the day of the examination, try not to discuss what you learned with your friends. This can lead to further confusion for both you and your friends. The way you may have learned a particular concept could be different as compared to the way your friends may have learned a particular topic. Apart from this you may also get confused as to if you missed any topics while studying or not. But don’t worry, you have given your best in your preparation and you will do well according to how you have studied.

These are tried and tested methods and have yielded results for lakhs of students like you all over the country. So, wishing you all the best for your preparation for the CBSE Class 9 Science examination . We advise you to be positive, confident as well as get the concepts clear for good exam performance and a high score. Also, revise the solutions to past question papers after understanding the content of the relevant chapters.

Numerical Problems from class 9 Motion (with solution)

Physics numericals class 9 from different chapters.

The next set of numerical questions (set 1) covers questions from the Motion chapter (kinematics) of class 9 physics and these can be easily solved using motion equations ( Suvat equations ).

Formulas Used

v=u + at s= ut + (1/2)at 2 s = [(u+v)/2]. t v 2 =u 2 + 2as

1) A speedboat has an acceleration of 2 m/s 2 . What would the final velocity of the speedboat be after 5 seconds if the initial velocity of the speedboat is 4 m/s?

a = 2 m/s 2 u = 4 m/s t = 5 s final velocity = v v = u + at = 4 + 2×5 = 14 m/s

2) A vehicle has an acceleration of 5 m/s 2 . What would the final velocity of the vehicle be after 10 seconds if the initial velocity of the vehicle is 20 m/s? What is the displacement of the vehicle during the 10 s time interval?

a = 5 m/s 2 u = 20 m/s t = 10 s final velocity = v v = u + at = 20 + 5×10 = 70 m/s final velocity = 70 m/s Displacement during the 10 s time interval = s s = ut + (1/2)at 2 => s = 20×10 + (½)x5x10 2 => s= 200 + 250 = 450 m Displacement during the 10 s time interval = 450 m

3) A child on a toboggan starts from rest and accelerates down a snow-covered hill at 0.8 m/s 2 . How long does it take the child to reach the bottom of the hill if it is 25.0 m away?

Solution: initial velocity u = 0 acceleration a = 0.8 m/s 2 distance = s = 25 m time taken t = ? s= ut + (1/2)at 2 As here, u = 0, so we can write: s= (1/2)at 2 => t 2 =(2 s /a ) = (2×25)/0.8 = 62.5 time t = 7.9 sec

4. A car accelerates uniformly from a velocity of 21.8 m/s to a velocity of 27.6 m/s. The car travels 36.5 m during this acceleration.

a) What was the acceleration of the car?

b) Determine the time interval over which this acceleration occurred.

a) final velocity v = 27.6 m/s initial velocity u = 21.8 m/s distance traveled s=36.5 m We will use this equation: v 2 = u 2 + 2as a = ( v 2 – u 2 ) /(2s) = (27.6 2 – 21.8 2 )/(2×36.5) = 3.92 m/s 2 Acceleration = 3.92 m/s 2 b) time interval over which this acceleration occurred = t v = u + at => t = (v-u)/a = (27.6-21.8) / 3.92 = 1.48 seconds.

5. A motorcycle starts from rest and accelerates at +2.50 m/s 2 for a distance of 150.0 m. It then slows down with an acceleration of –1.50 m/s 2 until the velocity is +10.0 m/s. Determine the total displacement of the motorcycle.

First part: displacement = s = 150 m We need to find out the final velocity(v) of this accelerating part. v 2 = u 2 + 2as => v 2 = 0 + 2×2.5×150 = 750 => v = 27.4 m/s This velocity becomes the initial velocity of the second part of the journey. Second part: u = 27.4 m/s a = -1.5 m/s 2 v= 10 m/s v 2 = u 2 + 2as 10 2 = 27.4 2 + 2.(-1.5).s => 100 = 750 – 3s s= 650/3 = 216.7 m Second part displacement = 216.7 m Considering a straight-line journey without a change of direction, total displacement = (150 + 216.7) m = 366.7 m

So let’s start with sets of Physics Numericals for Class 9 which contains Numerical problems & questions from various chapters of Class 9 physics with solutions & answers.

Problems based on Newton’s Second Law

F = ma m = F/a a = F/m F = (mv – mu)/t

1) A force of 1000 Newton is applied on a 25 kg mass for 5 seconds. What would be its velocity?

  Solution: F =1000 N m=25kg t= 5 sec u=0 v=? Acceleration = a = F/m = 1000/25 = 40 m/s 2  v = u + at =0 + 40X5 = 200 m/s

2) A force is applied to a mass of 16 kg for 3 seconds. As the force is removed the mass moves 81 meters in 3 seconds. What was the value of the force applied?

Solution: First 3 secs: Force is present, and in the next 3 secs Force is not there, so uniform velocity for the last 3 seconds is mentioned. In the last 3 seconds, the mass travels with uniform velocity (Where no force means there is no acceleration). So the velocity in the next 3 secs: V = 81/3 = 27 m/s This velocity was attained in the first 3 seconds when the force was present. So in the first 3 seconds, velocity changes from 0 to 27m/s. Therefore the acceleration in the first 3 seconds caused by the force present = (27-0)/3 = 9 m/s². So the force applied on the mass for first 3 secs= mass x acc = 16 x 9 = 144 N

3) A mass of 50 kg was moving with a velocity of 400 m/s. A force of 40000 N is applied to the mass and its velocity is reduced to 50 m/s after some time. What is the distance traveled by the mass during this period?

Solution: Mass = 50 kg u = 400 m/s v= 50 m/s F = 40000 N t = unknown Distance traveled in time t =? Acceleration = a = F/m = 40000/50 = 800 m/s 2 Again, acceleration a = change of velocity /t or, t = change of velocity/a = 350/800 sec Distance traveled: s = ut – (1/2)a t 2 = 400 * (350/800) – (1/2) 800. (350/800) 2 = 175 – 76.5 = 98.5 m

4) A ball of 150 g mass moves with 12 m/s and bounces back after hitting a wall with 20 m/s after a small duration of 0.01 seconds. What was the force applied to the ball when it hits the wall?

Solution: Mass = 150 gram = 150/1000 kg = 0.15 kg Change of velocity = 20 – (-12) = 32 m/s T = 0.01 sec Acceleration = change in velocity / time = 32/0.01 = 3200 m/s 2 Force = mass X Acceleration = 0.15 X 3200 N= 480 N.

5) Momentum of an object changes from 100 kg m/s to 200 kg m/s in 2 seconds. What is the force applied to it?

Solution: Note: Force = ma = m(v-u)/t = (mv – mu)/t = change of momentum /time = rate of change of momentum Force= change of momentum /time = (200-100)/2 = 100/2 = 50 N

6) A force of 200 N is applied to a body and its velocity changes from 5m/s to 10m/s in a second. What is the mass of the body?

Solution: mass = force/acceleration here acceleration =a = (10-5)/1 = 5 m/s 2 so, mass  = 200/5 kg = 40 kg

7) A mass of 1 kg is moving from east to west with a velocity of 10 m/s. A force is applied to it for 2 seconds and its velocity becomes 5 m/s. What is the value and direction of the force?

Solution: Mass = 1kg velocity = 10 m/s (east to west) Because of the force, the velocity reduces to 5 m/s in 2 secs. acceleration = change of vel/time=5/2 = 2.5 m/s 2 Force = mass X acceleration= 1 X 2.5 = 2.5 N. As the velocity reduces because of force, (negative acc i.e. retardation) hence the direction of the force would be opposite to the initial direction. So the direction of the force will be west to east.

Problems based on the Universal Law of Gravitation

F = GMm/r 2

8) If the distance between 2 objects is doubled then how will the gravitational force between them change?

Solution: F1 = GMm/r 2 F2 = GMm/(2r) 2 = GMm/4r 2 so F2/F1 = ¼ , so the final gravitational force will be ¼th of the initial gravitational force

9) If the distance between 2 objects is halved then how will the gravitational force between them change?

Solution: F1 = GMm/r 2 F2 = GMm/(r/2) 2 =4 GMm/r 2 so F2/F1 = 4/1 so the final gravitational force will be 4 times the initial gravitational force

10) If the masses of the 2 objects are doubled then how will the gravitational force between them change?

Solution: F1 = GMm/r 2 F2 = (G2M2m)/(r) 2 =4 GMm/r 2 so F2/F1 = 4/1 so the final gravitational force will be 4 times the initial gravitational force

PRACTICE REVIEW TEST

THE PHYSICS CLASSROOM TUTORIAL

A set of instructional pages written in an easy-to-understand language and complemented by graphics and Check Your Understanding sections. An ideal starting location for those grasping for understanding or searching for answers.

PHYSICS SIMULATIONS

The Physics Interactives includes a large collection of HTML5 interactive physics simulations. Designed with tablets such as the iPad and with Chromebooks in mind, this user-friendly section is filled with skill-building exercises, physics simulations, and game-like challenges.

PHYSICS VIDEO TUTORIAL

Our Video Tutorial provides a video-based alternative to the written Tutorial above. We aim to present relatively short, highly-organized presentations with a strong graphical component on discrete topics. Watch them on our site or follow the links to YouTube. We add videos quite frequently so stop back by if you don't find what you are looking for. Or subscribe to our YouTube channel,  tap the bell , and receive notifications when new videos come out.

MULTIMEDIA PHYSICS STUDIOS

A large collection of GIF animations and QuickTime movies designed to demonstrate physics principles in a visual manner. Each animation is accompanied by explanations and links to further information.

CONCEPT BUILDERS

Have you tried a Concept Builder lately? You should. This growing collection of cognitively-rich exercises will focus student attention on discrete learning goals. Filled with interactive elements, this section is the perfect tool for getting students thinking about the meaning of concepts. Perfect for students and 1:1 classrooms using iPads, Chromebooks, and the like. And for Chemistry types, we've added a large collection of Chemistry Concept Builders. 

MINDS ON PHYSICS - VERSION 5   

Minds On Physics - Version 5 is the HTML5 version of Minds On Physics that replaces our App and Legacy versions. Relying on a large bank of carefully crafted questions, Minds On Physics seeks to improve students' conceptions of physics. "MOPs" combines interactive questioning modules with a thorough, question-specific Help system to engage students in an exercise in thinking, reflecting, and learning. Version 5 is our best-yet version of Minds On Physics. There is a fully functional free version and a paid version that integrates seamlessly with our Task Tracker system and offers some rather enticing features.  

THE CALCULATOR PAD

Version 2 of the Calculator Pad is now available. Our newest version includes >2500 Physics and Chemistry problems organized into >250 ready-to-use problem sets. Numerical information is randomly-generated. An answer box allows students to solve and check their answers. Most problems are accompanied  by an audio-guided solution that explains how to solve a similar problem while hilighting the habits that can be adopted for solving any problem. Teachers with Task Tracker accounts can modify problems and problem sets and even create their own problems. Task Tracker also allows teachers to assign problems to their students and track their progress. 

CONCEPT CHECKERS  

Concept Checkers were built to coordinate with the Physics Interactives section of our website. Relying upon our Task Tracker tool to deliver questions, check answers, and track student progress, a Concept Checker is designed to coordinate with an interactive simulation. Use it as a follow-up check to understanding after exploring the simulation. Most sims are accompanied by a Concept Checker. Some sims have Task Tracker code built into the simulation. But not all sims will have a Concept Checker.  Concept Checkers can be used with or without a Task Tracker account. 

THE SCIENCE REASONING CENTER

The Science Reasoning Center is our most recent upgrade. This section includes about 70 activities that are perfect for encouraging scientific reasoning skills. Students use science and engineering practices, combined with cross cutting science concepts and core ideas from the disciplines of physics (and chemistry) to analyze phenomenon, experiments, and data presentations. We broke ground in April of 2023; we will continue work throughout the 2023-24 school year.

THE REVIEW SESSION

A collection of pages with questions and answers/explanations which serve as reviews or practice. Each review complements a chapter from The Physics Classroom Tutorial.

PHYSICS HELP

A variety of question-and-answer pages which target specific concepts and skills. Topics range from the graphical analysis of motion and drawing free body diagrams to a discussion of vectors and vector addition.

ACT TEST CENTER

Calling all high school juniors: You've trusted The Physics Classroom to help prepare you for that unit exam in physics. Why not trust us to help prepare you for the biggest test of the year - the ACT test? That's right. Let the TPC help you with the ACT.

CURRICULUM CORNER

A collection of classroom ready worksheets for use by teachers with their classes. Pages are synchronized to readings from The Physics Classroom Tutorial and to assignments of The Minds On Physics Internet Modules. And now teachers can purchase The Solutions Guide containing complete answers, explanations and solutions to all worksheets. This is a section of great usefulness to teachers and of little interest to students. The Solutions Guide is available as a Digital Download.

LESSON PLANS AND PACING GUIDES

We are building a collection of lesson plans and pacing guides for multiple units for a variety of course types. The lesson plans will provide teachers with a concrete demonstration of how resources at The Physics Classroom can be incorporated into a course. We will also have corresponding pre-built courses available for Task Tracker users that mirror the lesson plans viewed in this section. These pre-built courses allow teachers to easily hit the ground running  with their Task Tracker classes. We expect this project to be completed by August 1, 2024. Until then, we will release content incrementally as we complete it. Teachers can tap the link and view samples of what we currently have completed.

TEACHER PRESENTATION PACK

Our Teacher Presentation Pack is a downloadable product that includes nearly 190 Microsoft PowerPoint slide decks, about 170 animations and videos in .mp4 and .gif formats, too-many-to-count stand-alone images, and a Lesson Notes page for every slide deck. The slide decks are compatible with Google Slides. We did our best to make the product ready-to-use and at the same time fully customizable. It's a great tool in the toolbox for any early-career teacher, cross-over teacher, or even veteran teacher.

QUESTION BANK

Writing good tests and quizzes for your physics class just got a whole lot easier! With The Physics Classroom's Question Bank, physics teachers can quickly put together multiple choice and free-response quizzes and tests that target concepts discussed at The Physics Classroom website. The Question Bank is available for purchase as a both a CD resource and as a Digital Download. Use of the Question Bank requires the Microsoft Word application. (Answers are NOT included on the Question Bank.)

NGSS CORNER

Our newest section, the NGSS Corner assists teachers of Physics and Physical Science in aligning their curricula with the Next Generation Science Standards. Numerous resources are identified and their alignment with the NGSS is described.

TEACHER TOOLKITS

The Teacher Toolkits provide teachers with packages of online resources (simulations, movies, animations, demonstration ideas, etc.) that are organized around a topic and a set of learning objectives. These resources, when combined with the numerous resources on our own site, allow teachers to plan high-quality, engaging instruction and to map out a curriculum that is NGSS-based.

THE LABORATORY

While you explore the approximately 150 labs here at The Laboratory, you will likely generate some questions about how they are used and how you can use them. This page, and the pages it links to, are hoped to provide some answers to those questions.

THE PHOTO GALLERY

The Photo Gallery provides teachers a toolbox of physics-relevant photos from the wealth of photos on Flickr. The Photo Gallery offers teachers three things: access to photos, organized by topic; a collection of nearly 30 galleries; and an invitation to join this exciting project of capturing and sharing physics phenomenon with a camera. Of course, students are welcome to participate as well.
