Question

In a circular motion, the direction of velocity at any point is along the __ to the circle.

Answer 1

Consider a ball attached to a rope at one end. The ball is being rotated with a constant speed. When the rope is released the ball moves in the direction of the tangent at that point. This signifies that the direction velocity of the ball is along the tangent.

In a circular motion, the velocity is tangential at each point.
