The antonyms for the term "centripetal force" include centrifugal force, divergent force, outward force, and repulsive force. Unlike centripetal force, which acts towards the center of a circular motion, centrifugal force pulls away from the center and tries to fling an object outwards. Divergent force drives apart the elements of a system, while outward force relates to the force that causes an object to move away from another object. Lastly, repulsive force refers to the force that repels one object from another object. These antonyms of centripetal force represent the opposite direction and effect of the centripetal force, and are crucial concepts in understanding motion in physics.
