In the video above I work three gravitational potential energy problems.

The formula for gravitational potential energy equals,

Gravitational Potential Energy =

Mass x Gravity (9.8 m/sec^2) x Height

Sample Problems

What is the GPE of a rock of 2kg when it is lifted 11 meters off the ground?

A light fixture has a mass of 4 kilograms, falls from the ceiling and strikes the floor with a force of 800 J. How high was the light fixture?

A box of paper falls from a shelf that is 4 meters high and strikes the floor with a force of 132.3 Joules.

How much did the paper weigh ?
