Vocabulary
energy - the ability to do work. gravitational potential energy (PEG) - the stored energy of an object due to its position relative to a reference point on Earth; is equal to the mass of an object multiplied by the acceleration due to gravity multiplied by the height of the object relative to the reference point. kinetic energy (KE) - the energy of motion; equal to one half times mass times the square of the velocity of an object. law of conservation of energy - energy is never created or destroyed, it is transferred or transformed from one form to another. potential energy - stored energy that can come in a variety of forms such as spring, gravity, and chemical.
