Motion Class 9 Science (Physics) One-Shot (Full Chapter Revision) Concepts & MCQs | BYJU's Class 9

Motion Class 9 Science (Physics) One-Shot (Full Chapter Revision) Concepts & MCQs | BYJU's Class 9

In this Byjus Achievers: Early Batch Class 9 & Boards in 45 Days series, Saurabh Sir will do a complete revision on class 9 Science chapter, Motion.

Motion is the change of position and can be defined in terms of the distance moved. Depending on whether the velocity is constant or changing, the motion of an object can be categorised as uniform or non-uniform. In this class, Saurabh Sir will take you through all the important formulas, concepts, graphs, and MCQs to help boost your preparations for the board exams. Some of the topics covered by Sir in this class are motion, distance, displacement, speed, velocity, acceleration, uniform and non-uniform motion, and uniform circular motion. By the end of the class, you will be able to solve any type of questions related to these topics. Further, SIr discusses the distance-time graph, displacement-time graph, and velocity-time graph.

Here’s a homework question for you:

Question: For a uniform circular motion, which of the following is true?
A. Velocity remains constant but speed changes.
B. Both velocity and speed remain constant.
C. Speed remains constant but velocity changes.
D. Both velocity and speed change.

[archaks]

Sir thankyou for teaching inenglish because i am from the south and its easy to understand in english more than hindi

[AKD_]

Our school physics teacher name is also Saurabh. So glad to know this.

[jamesjames]

This class helped me very much..
I didn't thought that byjus classes are very easy to study than studying in schools and I am from Kerala ....
My name is Jobin

[arpananimates]

legends are watching one day before exam

[MotivateSuccess]

sir very good class
helped a lot before the exam 🙏

[khushisheoran]

Sir cover a class on uniform circulation motion

[kaynatfatima]

sir yesterday is my exam and 1 day before I see the video and it will very help me in my exam some questions are related from this video.. thanks BYJU so much for my help and thanks for clear my doubt

[study_tooper.]

Sir i am new and listen your lecture first time i really love it i also go in byjus tution in Mathura i really love

[dhairyasakhare]

thank u sir for such informative videos

[officialcrimsongamerZ]

Total distance is same for speed, avg speed. Then why do we use 2terms.

[animatripathy.]

I think the answer of homework question is 4s.

[naseemakm]

A car accilarrs uniform from 18 km/hr to 36 km/hr in 5 minutes. Caliculate the accilaration. Sr please do this....👈👈🤚

[innersphere]

Nice video, Made my clear, pls make revision videos for all other chapters

[zxgamer_]

Sir one question how do you get to know how much h should we draw the line for the rest in graph 📊

[Anjali_queen]

Sir please put the link of DERIVATION Sesioin please

[kushkush]

Distance covered by an object called distance?

[subharajaramv]

Hi sir will aiswarya mam take class for 9th grade

[Princekumar-dimy]

Sir prove graphicaly equation of motion

[manishsingh-ujwb]

Homework question:
In uniform circular motion speed remains constant but velocity changes .
Because direction is changing
