A student drops a piece of apparatus with a mass of 5kg from a height of 2m to the floor. What is the change of potential energy?

$U = m \times g \times h$

where

$U$ is the Potential Energy

$m$ is the mass

$g = 10ms^{-2}$ is the acceleration due to gravity

and $h$ is the height above the ground

So in this case,

$U = 5kg \times 10ms^{-2} \times 2m = 100kgm^2s^{-2} = 100J$
