Question

An object P is moving with a constant velocity for 5 min . Another object Q is moving moving with changing velocity for 5 min.Out of these two objects, which one has acceleration?Explain

Answer 1

Acceleration is defined as the rate of change of velocity.

Object P is in constant velocity, thus there is no change in the velocity with the change in time. Hence velocity is zero, thus acceleration is also zero.

In object Q there is change in the velocity thus acceleration is caused in the object Q.

Answer 2

HEY!!

_____________________________

⚫Object P is moving at a constant velocity.

⚫Hence there is no change in velocity and acceleration is the rate of change in velocity which is zero for object P.For object Q there is a change in velocity.

⚫Hence there should be acceleration if velocity is increasing or retardation if velocity is decreasing.
