How to analyze centrifugal motion and centripetal motion?

Centrifugation is to leave the center of motion of an object,

Centripetal force refers to the center of motion of an object.

It depends on the trajectory of the object and whether the moving object is outside or inside the circle.

Generally speaking, the outside of a circle is centrifugal and the inside of a circle is centripetal.

Make a particle vector diagram.

According to some conservation principles, write the equation. Just find out the unknown.

The most important thing is to know what conservation laws are needed for the meaning of the problem.
