A particle in uniform circular motion requires a net force acting in what direction?

A. Towards the center of the circle.

B. In the direction of velocity.

C. Opposite the direction of the velocity.

D. Away from the center of the circle.

E. Upward.

F. Downward

Answer: A) Towards the center of the circle.

## Explanation

The net force acting on such an object is directed towards the center of the circular path. This force is called the centripetal force, without the centripetal force, the object would move in a straight line, without any deviation from its direction.

The centripetal force pushes things in a curved line. It’s typically aimed at the middle of the circle. In order for a uniform circular motion to occur, the radial component of the force must always be zero (otherwise the object will speed up or slow down, resulting in non-uniform motion).

As a result, the net force should be directed toward the center of the circle. Otherwise, the thing will shatter from its circular route or its motion will become non-uniform.
