## Work From Velocity Formula

The following formula is used to calculate the Work From Velocity.

W = 1/2*m*dV^2

- Where W is the Work From Velocity (J)
- m is the mass (kg)
- dV is the change in velocity/speed (m/s)

To calculate work from velocity, multiply the mass times the change in velocity squared, then divide by 2.

## How to Calculate Work From Velocity?

The following two example problems outline how to calculate the Work From Velocity.

**Example Problem #1:**

- First, determine the mass (kg). In this example, the mass (kg) is given as 81.
- Next, determine the change in velocity/speed (m/s). For this problem, the change in velocity/speed (m/s) is given as 58.
- Finally, calculate the Work From Velocity using the equation above:

W = 1/2*m*dV^2

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

W = 1/2*81*58^2= 136,242 (J)

**Example Problem #2: **

Using the same process as above, first define the variables required by the formula. In this case, these values are:

mass (kg) = 94

change in velocity/speed (m/s) = 10

Entering these values yields:

W = 1/2*m*dV^2 = 4700 (J)
