PE and KE Quiz 1

A 250 kg caribou is standing on top of a 20 meter hill. How much gravitational potential energy does the caribou have?

• 49,050 J

• 5,000 J

• 0.98 J

• 509.68 J

The equation for POTENTIAL ENERGY is

• PE = mass x gravity x height

• PE = gravity x weight

• PE = height / work

• PE = work / time
