The force that causes moving objects in a circle to be pushed outward is called centrifugal force. However, it's important to understand that centrifugal force is not a real force.

Here's the explanation:

* Centripetal force is the actual force that keeps an object moving in a circle. It acts towards the center of the circle. This force is what is causing the object to change direction constantly.

* Centrifugal force is an inertial force. It's a fictitious force that arises from the object's tendency to move in a straight line (Newton's First Law of Motion). The object wants to continue moving in a straight line, but the centripetal force is constantly pulling it inwards, causing it to move in a circle. The "outward push" feeling is the result of the object resisting this inward pull.

Think of it this way: Imagine you're swinging a ball on a string. The string provides the centripetal force, pulling the ball towards your hand (the center of the circle). The ball feels like it's being pushed outwards by centrifugal force, but this is just the ball's inertia trying to continue moving in a straight line.

In summary, while the term "centrifugal force" is used to describe the outward feeling, it's not a real force in the same way that gravity or friction are real forces. It's a consequence of inertia acting on an object moving in a circular path.
