Given

m: mass

m = 1kg

h: height

h = 2.5m

Procedure

Gravitational potential energy, stored energy that depends upon the relative position of various parts of a system.

PEgrav = m • g • h

In the above equation, m represents the mass of the object, h represents the height of the object and g represents the gravitational field strength


\begin{gathered} U=\text{mgh} \\ U=1\operatorname{kg}\cdot9.8m/s^2\cdot2.5m \\ U=24.5J \end{gathered}
