Question

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

Answer 1

$\underline\purple{\underline{\bf{\maltese\: Answer\::-}}}$

✧ 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.

Hope it helps :)

Answer 2

Answer:

✧ 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.
