As the centripetal force acts upon an object moving in a circle at constant speed, the force always acts inward as the velocity of the object is directed tangent to the circle. This would mean that the force is always directed perpendicular to the direction that the object is being displaced.

Which forces can act as a centripetal force?

Any force that causes an object to move in a circle is a centripetal force. Gravity, tension, friction, and other forces can all act as centripetal forces; all of these forces can act to pull or push an object into a circle.

What is an example of centripetal force acting?

The revolution of the moon around the earth and the spinning of the top are some examples of centripetal force.
