Gravitational Potential Energy Problems

Thursday, April 28, 2022


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 ?
