ENERGY: the capacity to do WORK
WORK: changing the state of something (FORCExDISTANCE)
FORCE: The cause, or agent, that puts an object at rest into motion or alters the motion of a moving object. (Webster) FORCE=MASSxACCELERATION
ACCELERATION: The rate of change in the Velocity of a moving object.(Webster)
A=DISTANCE divided by TIME squared
