Acceleration of a particle changes when

A

direction of velocity changes

B

magnitude of velocity changes

C

Both (a) and (b)

D

speed changes

Text Solution

Verified by Experts

The correct Answer is:
C
Acceleration is a vector quantity. So, it changes when both magnitude and direction of velocity change.
