Physics Concepts

(a) The net acceleration of a particle in circular motion is always along the radius towards the center.

False

Only true for uniform circular motion. In non-uniform motion, there's also tangential acceleration.

(b) The velocity vector is always tangent to the path of the particle.

True

Velocity is always tangent to the path in any circular motion.

(c) The acceleration vector averaged over one cycle is a null vector in uniform circular motion.

True

The direction changes continuously, averaging to zero over a full cycle.
