## Free Fall Energy Formula

The following equation is used to calculate the Free Fall Energy.

**FFE = m*g*h**

Variables:

- Where FFE is the Free Fall Energy (Joules)
- m is the mass of the falling object (kg)
- h is the height of the fall (m)
- g is the acceleration due to gravity (m/s^2)

## How to Calculate Free Fall Energy?

The following two example problems outline the steps and information needed in order to calculate the Free Fall Energy.

**Example Problem #1:**

- First, determine the mass of the falling object (kg). In this example, the mass of the falling object (kg) is measured to be 50.
- Next, determine the height of the fall (m). For this problem, the height of the fall (m) is calculated to be 40.
- Finally, calculate the Free Fall Energy using the formula above:

FFE = m*g*h

Inserting the values from above and solving the equation with the imputed values gives:

FFE = 50*9.81*40 = 19,620 (Joules)

**Example Problem #2: **

Using the same process as example problem 1, we first define the needed variables outlined by the formula. In this case, the values are provide as:

mass of the falling object (kg) = 31

height of the fall (m) = 45

Entering these values into the formula or calculator above gives us:

FFE = 45*9.81*31 = 13,684.95** **(Joules)
