Objective:
What is the difference between gravitational, elastic, and chemical potential energy?
What is the relationship between potential and kinetic energy?
ENERGY
KINETIC ENERGY• When an object is moving.
MECHANICAL ENERGY• The combination of potential and kinetic energy
(rest+motion)
• Energy associated with the motion of an object.
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.
REALITY CHECK• What is the difference between gravitational, elastic, and chemical
potential energy?
