Enter the mass of the object (kg) and the translational velocity (m/s) into the calculator to determine the Translational Kinetic Energy. 

Translational Kinetic Energy Formula

The following equation is used to calculate the Translational Kinetic Energy. 

KEt = .5*m* Vt^2


  • Where KEt is the Translational Kinetic Energy (Joules)
  • m is the mass of the object (kg) 
  • Vt is the translational velocity (m/s) 

To calculate the translational kinetic energy, multiply the mass by the translational velocity squared, then divide by 2.

How to Calculate Translational Kinetic Energy?

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

Example Problem #1:

  1. First, determine the mass of the object (kg). In this example, the mass of the object (kg) is measured to be 5.
  2. Next, determine the translational velocity (m/s). For this problem, the translational velocity (m/s) is calculated to be 4.
  3. Finally, calculate the Translational Kinetic Energy using the formula above: 

KEt = .5*m* Vt^2

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

KEt = .5*5* 4^2 = 45 (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 object (kg) = 3

translational velocity (m/s) = 2

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

KEt = .5*3* 2^2 = 6 (Joules)
