Enter the total speed (m/s) and the mass of the moving object (kg) into the calculator to determine the Energy from Speed.

## 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:

1. First, determine the total speed (m/s). In this example, the total speed (m/s) is measured to be 571.
2. Next, determine the mass of the moving object (kg). For this problem, the mass of the moving object (kg) is calculated to be 48.
3. 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)
