) Plot the graph of distance time when object is at rest?
What do you mean by average speed?
Rest and motion are relative to each other?
Draw the graph of uniform and non-uniform acceleration?
Can a body have a zero velocity and finite acceleration? Explain.
Write the difference between distance and displacement.
(3)
Draw velocity-time graph for uniform and non-uniform motion.

A ball is gently dropped from a height of 20m. If its velocity increases uniformly at the rate of 10m
velocity will it. Strike the ground? After what time will it strike the ground?
An athlete completes one round of a circular track of diameter 200m in 40sec. What will be the distance cove
displacement at the end of 2 minutes 20 sec?

Answer:
All graph based questions are on this attachment photo
What do you mean by average speed?
Average speed is Total Distance/Total time
Rest and motion are relative to each other?
Yes, Rest happens when motion doesn't and vice versa
Can a body have a zero velocity and infinite acceleration? Explain.
I think there was a typo in the question so I corrected it, Yes, in uniform circular motion
Write the difference between distance and displacement.
Distance has only magnitude as it is a scalar quantity, whereas, Displacement has both magnitude and direction as it is a vector.
A ball is gently dropped from a height of 20m. If its velocity increases uniformly at the rate of 10m
velocity will it. Strike the ground? After what time will it strike the ground?
u=0
S=20
a=10
t=?
S=1/2 at^2
therefore
t=2 secs refer file
