Motion In A Plane

Question

Read the statement below carefully and state, with reasons, if it is true or false:

A.
The acceleration vector of a particle in uniform circular motion averaged over one cycle is a null vector

Solution

A. TRUE

Tips: -

The direction of acceleration vector in a uniform circular motion is directed towards the centre of circular path. It is constantly changing with time. The resultant of all these vectors will be zero vector.
