Kinetic Energy Calculator

Calculate kinetic energy from mass and velocity

How to Use
  1. Select the variable you want to solve for: Kinetic Energy, Mass, or Velocity.
  2. Enter the values for the remaining two variables.
  3. Click Calculate to find the missing value.

Formula

Kinetic Energy formulas:

  • KE = ½ × m × v²
  • m = (2 × KE) ÷ v²
  • v = √( (2 × KE) ÷ m )

Where KE is Kinetic Energy in Joules (J), m is mass in kilograms (kg), and v is velocity in meters per second (m/s).
