# Potential Energy Definition

In physics, potential energy is defined as the energy reserved in an object at a specific place or height. Or in other words, it is determined as the energy stored in an object when it is at a resting position. This SI unit used to measure P.E is Joules. For instance, when an arrow is stretched in a bow, it stores elastic potential energy in it, and when archery releases an arrow, it converts into kinetic energy. For a more precise understanding let's see the image below:

Gravitational potential energy, elastic potential energy (or spring energy), and electrical potential energy are the few types of potential energy.

## Formula of Potential Energy

The formula used for potential energy is:

PE = m * g * h

Where,

PE = potential energy

m = mass of the object

g = gravitational acceleration

h = height from sea level

Note:

To calculate potential energy, you can use our Potential Energy Calculator.

### Example

Suppose, we have an object placed at a height of 10m with a mass of 5kg. What will be its potential energy?

Given data

h = 10m
m = 5kg
g = 9.8

To Find

Potential Energy = ?

Solution

To find the potential energy, we can use the formula listed below:

PE = m * g * h

Putting values in the formula:

PE = 5 * 9.8 * 10 = 490
