Question

Mention the uses of velocity time graph

Answer 1

it tells is about traveled distance
about speed it is constant or non constant
whether it is at rest or in motion
many more

Answer 2

A 'velocity-time graph' can be used for the following ways:

• To determine the speed of a body at any given instant of time.

• To determine the acceleration of the body.  

• To determine the nature of motion of a body.

• To determine the displacement of a body.

• To determine the 'total distance' traveled by a body.

• A 'velocity-time graph' is useful for the mapping which means the recording of the velocity of a body at different time intervals.
