# What is the gravitational potential energy of a  1 kg object on a shelf  2/9 m  high?

Feb 1, 2016

$\approx 2.18 N m$
Gravitational potential energy is calculated from the produce of the object's mass, it's height above ground, and the acceleration due to gravity $g$.
$G P E = m \cdot g \cdot h$
In this example $G P E = 1 \cdot 9.8 \cdot \frac{2}{9}$
$\approx 2.18 N m$
