# What is the gravitational potential energy of a  12 kg object on a shelf  3 m  high?

Apr 12, 2018

$352.8 \setminus \text{J}$

#### Explanation:

Gravitational potential energy is given by the equation,

$\text{GPE} = m g h$

• $m$ is the mass of the object in kilograms

• $g$ is the gravitational acceleration, which is approximately $9.8 \setminus {\text{m/s}}^{2}$

• $h$ is the height of the object in meters

And so, we got:

$\text{GPE"=12 \ "kg"*9.8 \ "m/s"^2*3 \ "m}$

$= 352.8 \setminus \text{J}$
