Question

If a body moves continously on a circular path with constant speed,an acceleration activate. At which point the velocity of the body will change?

Answer 1

When a body moves on a circular path with a constant speed, then the motion of the object is said to be a uniform circular motion. In uniform circular motion, the magnitude of the velocity of the object remains constant. However, the direction of velocity vector changes continuously. It is represented by the tangent to the circular path at a given instant. Thus, at every point, the magnitude of the velocity will remain the same and the point will show only the current direction.
