Question

A body having uniform velocity has zero acceleration

Answer 1

a = (V2 - V1) / t = 0 if V2 = V1

True

Note: an object moving in a circular path with a uniform speed does not have a uniform velocity

Answer 2

Acceleration means change in velocity with respect to time If the body is moving with uniform velocity then there will be no change in velocity which means acceleration will be 0.
