Here's the breakdown:
What really happens:
* Inertia: When an object spins, it wants to continue moving in a straight line (due to inertia). However, the spinning motion forces the object to constantly change direction, thus requiring a force to keep it moving in a circle.
* Centripetal force: This is the inward force that is necessary to keep the object moving in a circular path. It's always directed towards the center of the rotation.
* Apparent outward force: It's the *feeling* of an outward force we experience while spinning. This feeling is due to our inertia trying to keep us moving in a straight line, while the spinning motion forces us to change direction.
The takeaway:
There is no outward force acting on a spinning object. The feeling of an outward force is simply our inertia resisting the change in direction caused by the spinning motion.
Analogy:
Imagine you're holding a ball on a string and swinging it in a circle. The string provides the centripetal force, pulling the ball inwards. The ball doesn't experience an outward force, it's just that its inertia wants to keep it moving in a straight line, so it's pulled inwards by the string.
