The so-called centripetal force refers to the resultant force produced when an object moves in a uniform circular motion. It can be just a collection of forces or a collection of many forces. So we often say that "some forces provide centripetal force."
Centrifugal phenomenon refers to the phenomenon that the speed of an object exceeds the speed value that can be fitted by centripetal force and radius, which leads to the object moving away from the center of the circle. It is called.
Centrifugal force: In the process of providing centripetal force by external force, the sum of reaction forces (the sum of forces is not a resultant force, because there may be more than one acting object, so it is not necessarily a resultant force) is opposite to the centripetal force and has the same magnitude. This abstract sum is called centrifugal force. It shows the pressure and pull of a uniform circular object on the centripetal force provider or other things.
