Marila Lombrozo When an object of mass m is raised through a vertical height $∆h$, the gain of its gravitational potential energy is $∆E_P$.
$∆E_P$ and $∆h$ are related by the equation
$\Delta E_p = mg\Delta h$
where $g$ is the acceleration of free fall.
The definition of which physical quantity is needed to derive this equation?
