Centrifugal force is the outward force that seems to push an object away from the center of rotation. It's not actually a real force but rather an inertial force felt by an object due to its tendency to move in a straight line.

Centripetal force is the inward force that keeps an object moving in a circular path. This force is real and acts towards the center of the circle.

Think of it like this:

* Centripetal force is like the string holding a ball on a circular swing, pulling it inwards.

* Centrifugal force is the feeling the ball experiences, wanting to fly outward.

So, the outward force you're looking for is centrifugal force.
