Objects can spin or orbit or rotate around balance point {rotation, force}. Rotations rotate around point {center of rotation} {rotation center} {balance point}. Forces or weights are at distances {radius, rotation} from balance point or rotation center. On levers, forces can act perpendicular, or at an angle, to radius. Weighing balances and seesaws are levers. Weights on strings can orbit, so string provides centripetal force, and spin provides centrifugal force.
