## Energy from Speed Formula

The following equation is used to calculate the Energy from Speed.

**E = .5*S^2*m**

Variables:

- Where E is the Energy from Speed (Joules)
- S is the total speed (m/s)
- m is the mass of the moving object (kg)

## How to Calculate Energy from Speed?

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

**Example Problem #1:**

- First, determine the total speed (m/s). In this example, the total speed (m/s) is measured to be 571.
- Next, determine the mass of the moving object (kg). For this problem, the mass of the moving object (kg) is calculated to be 48.
- Finally, calculate the Energy from Speed using the formula above:

E = .5*S^2*m

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

E = .5*571^2*48 =7824984 (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:

total speed (m/s) = 59

mass of the moving object (kg) = 44

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

E = .5*59^2*44 = 76,582** **(Joules)
