Question

An object is moving on a circular path with velocity vector v at a given instant. When it completes half rotation what will be the change in its velocity??
(A) v
(B) -2v
(C) zero
(D) â2 v

Answer 1

Answer:

When a particle moves in a circular path with uniform speed, its angular velocity remains constant i.e. both the direction and magnitude of the angular velocity remain same. The magnitude will depend on the speed of the particle and the direction is always perpendicular to the plane of motion

Explanation:

a.V
