Learning Objectives

-Quantitatively and qualitatively define kinetic energy and gravitational potential energy.

-Review the law of conservation of energy and relate it to changes in the types of energy an object possesses as it moves.

-Explain how conversions from one type of energy to another can be helpful in real-life situations.

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.
