Enter the mass of the object (kg) and the escape velocity (m/s) into the Calculator. The calculator will evaluate the Escape Energy. 

Escape Energy Formula

EE = 1/2*m*ev^2


  • EE is the Escape Energy (J)
  • m is the mass of the object (kg)
  • ev is the escape velocity (m/s)

To calculate Escape Energy, multiply the mass by the escape velocity squared, then divide by 2.

How to Calculate Escape Energy?

The following steps outline how to calculate Escape Energy.

  1. First, determine the mass of the object (kg). 
  2. Next, determine the escape velocity (m/s). 
  3. Next, gather the formula from above = EE = 1/2*m*ev^2.
  4. Finally, calculate the Escape Energy.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

mass of the object (kg) = 400

escape velocity (m/s) = 500
