Did you know?

Ever watch a top spin? Or see one pool ball collide with another and send it across the felt? When you do, you’re witnessing kinetic energy—the energy of something in motion. Kinetics is a branch of science that deals with the effects of forces upon the motions of material bodies, and something described as kinetic has to do with the motion of material bodies and the forces associated with them. Both words were adopted in the 19th century from the Greek word kinētikos (meaning "of motion") for use in the field of physics, but the adjective kinetic proved too apt for broader application, and by the 1930s it was being used to describe people and things full of literal and figurative energy as well.
