(a) The net acceleration of a particle in circular motion is always along the radius of
the circle towards the centre
(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​
