central force [′sen·trəl ′fȯrs] (mechanics) A force whose line of action is always directed toward a fixed point; the force may attract or repel. Central force A force whose line of action is always directed toward a fixed point. The central force may attract or repel. The point toward or from which the force acts is called the center of force.

Undisturbed orbital motion under the influence of a central force satisfies Kepler's law of areas. How to thank TFD for its existence?
