In this Mission Mid-Terms series, your favourite BYJU’S educator, Saurabh Sir discusses class 9 Science Chapter 8, Motion in detail.
Motion is a change of position and it can be described in terms of the distance moved. Depending on whether its velocity is constant or changing, the motion of an object could be uniform or non-uniform. Some of the topics that will be covered through this Menti quiz are as follows:
- Speed
- Uniform and non-uniform motions of objects
- The equation for position-time relation
- Equations of motion by graphical method
- Velocity-time graph and distance-time graph
- Speed, velocity and acceleration
- Circular motion
We at BYJU'S always strive to give you the best. Add this video to your study plans to amplify your chances of cracking the Exam!

[@Lucky-py7hv]

does it matter

[@Sainathpawar2009]

Acceleration is the name we give to any process where the velocity changes. Since velocity is a speed and a direction, there are only two ways for you to accelerate: change your speed or change your direction-or change both.

[@fireballs882]

when sir asked can u describe the position of train i saw chat and realised no one even opened the textbook.....the answer is we cannot describe the position of object because we dont have reference point

[@shristhetic7283]

47:20 sir this means the displacement will be 0 ?because the body again reaches the initial position

[@23kolQAhuY-yt]

Yes. You're right. When an body reaches its initial point after covering a particular distance, the displacement would be marked as 0

sir what is the meaning of vector quantity and scalar.quantity vector quantity and

[@shadowcadet898]

scalar quantity only has magnitude (speed) while vector quantity has both magnitude and direction (velocity) hope this helps :)

[@channabasappasajjan4756]

Good evening sir

[@malathikitchen377]

Sir is displacement have short distance and the distance have long distance is it right sir

[@vijayalbert6791]

yeah, the displacement is the shortest path and the distance is the actual path of an object

[@SnehaSharma-qf1xx]

Things were quite complex and .... too

[@mithileshsinghmithileshsin6075]

yes

[@user-hr2xd4fy9w]

21:14 clip me you have said that displacement both negative bhi ho sakta hai aur positive bhi so why not in distance it can be negative [aap ne likha hai it will be positive for a body in motion] mujhe samaj nahi aaya actually pls pls sir can I get ans fast jaldi dekhlo mera question

[@shwetadixit6712]

@user-hr2xd4fy9w distance cannot be in negative because the minimum distance is 0 which is also known as rest..so the distance can only be calculated when an object moves and obviously object cannot moves in with respect to negative distance
