What is the direction of the centripetal force when applied to an object?

Direction of Centripetal force would be "TOWARDS CENTER" when applied to an object.

The direction of centripetal force is always orthogonal to the motion of object.

Explanation:

Centripetal force is force which compels an object to move in the circular path with the constant speed. The direction of velocity of object is always tangent to the circular path. Because in circular motion, it is important to maintain constant speed so, object can only be accelerated by changing the direction of velocity. The direction of velocity can only be changed if the direction of centripetal force is perpendicular to motion of the object (towards center).

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
