# What is the gravitational potential energy of a  1 kg object on a shelf  5 m  high?

$45 J$

#### Explanation:

Gravitational Potential Energy is denoted by the formula

$G P E = m g h$

Where

$G P E$ = gravitational potential energy ($J$)
$m$ = mass ($k g$)
$g$ = acceleration due to gravity ($m {s}^{-} 2$)
$h$ = height ($m$)

Substitute the values you have into the formula

$G P E = 1$x$9.8$x$5$

$\therefore$ $G P E = 45 J$
