Energy Equations Practice

This quiz uses the equations for kinetic energy, gravitational potential energy, and spring potential energy.

$E_k =\cfrac{1}{2}mv^2$

$E_g = mgh$

$E_s = \cfrac{1}{2}kx^2$

(Use g = 9.8 m/s² as the acceleration due to gravity to get your answers to match the quiz answers)
