Question

Explain why, the motion of a body which is moving with constant speed in a circular path is said to be accelerated.

Answer 1

The motion of a body with constant speed in a circular path is said to be accelerated,
because it is moving with uniform speed, but not with uniform velocity, as velocity is a vector quantity, it can be represented in magnitude as well the direction. Though the magnitude doesn't changes, the direction changes in a circular motion, so the object is said to be in acceleration
