Calculate the amount of elastic potential energy stored in a stretched spring (assuming the limit of proportionality is not exceeded) using the equation:

E_e = \frac{1}{2} k e^2

Calculate the amount of gravitational potential energy gained by an object raised above ground level using the equation:

E_p = m g h
