**disclaimer: I KNOW the apple story might not be true, but everyone has heard about it, so...

** if a problem does not give you g, g = 9.8 m/s²

Multiple Choice

Energy stored by objects due to their position above Earth’s surface.

• potential energy

• kinetic energy

• gravitational potential energy

• mechanical energy

Multiple Choice

What is the unit of measurement for potential energy?

• Watts

• Joules

• Newtons

• Meters

Multiple Choice

I have the most potential energy if I am:

• 5 feet high

• 10 feet high

• 15 feet high

• 20 feet high

GPE = mgh

GPE = 7 kg * 9.8 m/s² * 4 m

GPE = 68.6 * 4

GPE = 274.4 Joules
