Question

what is the direction of velocity of a particle performing uniform circular motion​

Answer 1

Answer:

tangent to the circle at that point.

Explanation:

Uniform circular motion can be described as the motion of an object in a circle at a constant speed. As an object moves in a circle, it is constantly changing its direction. At all instances, the object is moving tangent to the circle. Since the direction of the velocity vector is the same as the direction of the object's motion, the velocity vector is directed tangent to the circle as well.

Answer 2

Answer:

An object undergoing uniform circular motion is moving with a constant speed.

Nonetheless it is accelerating due to its change in direction. The direction of the acceleration is inward.
