The image above represents potential energy.

To compute for the potential energy, three essential parameters are needed and these parameters are **mass (m), ****height (h) **and **acceleration due to gravity (g)****.**

The formula for calculating the potential energy:

P.E = mgh

Where;

P.E. = Potential Energy

m = Mass

g = acceleration due to gravity

h = Height

Let’s solve an example;

Find the potential energy when the mass is 12 with a height of 24 and acceleration due to gravity of 9.8.

This implies that;

m = Mass = 12

g = acceleration due to gravity = 9.8

h = Height = 24

P.E = mgh

P.E = 12 x 9.8 x 24

P.E = 2822.4

Therefore, the **potential energy** is **2822.4 Joules (J)**.

**Calculating the Mass when Potential Energy, Height and Acceleration due to Gravity is Given.**

m = ^{P.E} / _{gh}

Where;

m = Mass

P.E. = Potential Energy

g = acceleration due to gravity

h = Height

Let’s solve an example;

Find the Mass when potential energy is 450 with a height of 30 and acceleration due to gravity of 10.

This implies that;

P.E. = Potential Energy = 450

g = acceleration due to gravity = 10

h = Height = 30

m = ^{P.E} / _{gh}

m = ^{450} / _{10 x 30}

m = ^{450} / _{300}

m = 1.5

Therefore, the **mass** is **1.5.**

**Calculating the Height when Potential Energy, Mass and Acceleration due to Gravity.**

h = ^{P.E} / _{mg}

Where;

h = Height

m = Mass

P.E. = Potential Energy

g = acceleration due to gravity

Let’s solve an example;

Find the Height when potential energy is 500 with a mass of 25 and acceleration due to gravity of 10.2.

This implies that;

P.E. = Potential Energy = 500

g = acceleration due to gravity = 10.2

m = Mass = 25

h = ^{P.E} / _{mg}

h = ^{500} / _{25 x 10.2}

h = ^{500} / _{255}

h = 1.96

Therefore, the **height** is **1.96**.
