What is Kinetic Energy?

Kinetic energy is the energy possessed by an object due to its motion. It depends on the mass of the object and the square of its velocity.

Kinetic Energy Formula

The formula for kinetic energy is:

KE = ½ × m × v²

Where:

  • KE = Kinetic Energy (Joules)
  • m = Mass (kg)
  • v = Velocity (m/s)

How to Use the Calculator

  1. Enter the mass of the object in kilograms
  2. Enter the velocity of the object in meters per second
  3. Click "Calculate" to get the kinetic energy
  4. View the step-by-step solution

Example Calculation

If a car with mass 1000 kg is moving at 20 m/s:

KE = ½ × 1000 kg × (20 m/s)²

KE = ½ × 1000 × 400

KE = 200,000 Joules
