Question

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

Answer 1

Answer:object Q has acceleration

Explanation:because we know that acceleration means change of velocity in time. As object Q is changing its velocity for 5mins thus it has acceleration.

Answer 2

Answer:

Definition of acceleration is change in velocity over time

So the acceleration of object P is 0 m/s/5min = 0m/s^2

It is 0 as , change in velocity is 0 as velocity is constant

Object Q is moving with a changing velocity for 5 min

so Its velocity must be changing as it is told in the question and hence it must have an accleration

as acceleration is change in velocity / change in time (The time for both the cases is from time = 0 min to time = 5 minutes)
