Read each statement below carefully and state, with reasons, if it is true or false :
(a) The net acceleration of a particle in circular motion is always along the radius of the circle towards the center.
(b) The velocity vector of a particle at a point is always along the tangent to the path of the particle at that point.
(c) The acceleration vector of a particle in uniform circular motion averaged over one cycle is a null vector.

Explanation

a) False, the net acceleration of a particle in circular motion is along the radius of the circle towards the center only in uniform circular motion.
True, because while leaving the circular path, the particle moves tangentially to the circular path.
c) True,the direction of acceleration vector in a uniform circular motion is directed towards the center of circular path. its is constantly changing with time. The resultant of all these vectors will be a zero vector.
