1, centripetal movement refers to the movement of an object near the center of the circle when the centripetal force provided by the object is greater than the required centripetal force.

2. Centrifugal motion refers to the uniform circular motion of an object. When the resultant force suddenly disappears or is insufficient to provide the required centripetal force, it will move away from the center of the circle. This movement is called "centrifugal movement".
