Figure given below shows a velocity-time graph for a car starting from rest. The graph has three parts AB, BC and CD.

Which part of graph shows motion with uniform
(a) velocity (b) acceleration (c) retardation ?
When is the acceleration due to gravity positive?
Draw velocity – time graph for the following situation:
When a body is moving with variable velocity and variable acceleration.
The speed of a car increases from 10 km/h to 64 km/h in 10 seconds. What will be its acceleration?
State if the following situation is possible:
A body moving with a constant velocity in an accelerated motion.
The graph shows how the velocity of a scooter varies with time in 50 s.
Work out: Deceleration
A car starts from rest and it is travelling with a velocity of 20 m/s in 10 s. What is its acceleration?
Assertion: The accelerated motion of an object may be due to change in magnitude of velocity or direction or both of them.
Reason: Acceleration can be produced only by change in magnitude of the velocity. It does not depend the direction.
