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) 

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)
