Mark the correct statements (s)....

Mark the correct statements `(s)`.

A

if speed of a body is varying, its velocity must be varying and it must have zero acceleration

B

if velocity of a body is varying, its speed must be varying

C

a body moving with varying velocity may have a constant speed

D

a body moving with varying speed may have constant velocity if its direction of motion remains constant.

Text Solution

Verified by Experts

The correct Answer is:
C
If speed of a particle changes, the velocity of the particle definitely changes and hence the acceleration of the particle is nonzero.
Velocity of a particle change without change in speed.
When speed of a particle varies, its velocity cannot be constant.
