Physics – Motion (Simple Study Notes
with Q&A)
These notes explain the chapter Motion in very simple language with examples, quick
memory points, and practice questions. They are useful for beginners and for quick exam
revision.
1) What is Motion?
Q: What is motion?
A: Motion is the change in position of an object with respect to a reference point in a given
time.
Example:
Moving a computer mouse
A car driving on a road
A rotating ceiling fan
Earth rotating on its axis
A ball swinging on a string
Memory Points:
Change in position → Motion
No change in position → No motion
Motion always needs time
Motion is measured using a reference point
2) Distance and Displacement
Q: What is distance?
A: Distance is the total path travelled by an object from the starting point to the ending
point. It does not depend on direction.
Q: What is displacement?
A: Displacement is the shortest straight-line distance between the starting point and the
final point. It includes direction.
