Enter the mass (kg) and the change in velocity/speed (m/s) into the calculator to determine the Work From Velocity. 

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:

  1. First, determine the mass (kg). In this example, the mass (kg) is given as 81.
  2. Next, determine the change in velocity/speed (m/s). For this problem, the change in velocity/speed (m/s) is given as 58.
  3. 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)
