Gravitational Potential Energy

What you need to know

Calculate the precise amounts of gravitational potential energy associated with raising an object above ground level.
Understand the physical principle that an object raised above ground level actively gains gravitational potential energy.
Recall and correctly apply the equation to calculate changes in stored energy:

$E_p = m g h$

=

mgh

Identify the correct units for gravitational potential energy in joules, mass in kilograms, gravitational field strength in newtons per kilogram, and height in metres.
Perform complex energy calculations utilizing given values for gravitational field strength.
