Objective: What is the difference between gravitational, elastic, and chemical potential energy? What is the relationship between potential and kinetic energy? ENERGY

POTENTIAL ENERGY When an object is NOT moving.

KINETIC ENERGY When an object is moving.

KINETIC VS. POTENTIAL A B

A B C

REALITY CHECK What is the relationship between potential and kinetic energy?

MECHANICAL ENERGY The combination of potential and kinetic energy (rest+motion ) Energy associated with the motion of an object.

GRAVITATIONAL POTENTIAL ENERGY Energy an object has due to its height and weight.

GRAVITATIONAL POTENTIAL ENERGY At which point will the ball have the greatest amount of gravitational potential energy? A B

GRAVITATIONAL POTENTIAL ENERGY At what point will the roller coaster have the least amount of gravitational potential energy?

GRAVITATIONAL POTENTIAL ENERGY At what point will the roller coaster have the most amount of gravitational potential energy?

ELASTIC POTENTIAL ENERGY Energy that allows you to change the shape of an object by stretching it.

ELASTIC POTENTIAL ENERGY Examples:

Elastic Potential Energy Which has greater potential energy? A. B.

CHEMICAL POTENTIAL ENERGY POTENTIAL ENERGY STORED IN CHEMICAL BONDS.
