About Energy Calculator

Computes kinetic energy of motion ($E_k = frac{1}{2}mv^2$) or potential energy stored within a gravitational field ($E_p = mgh$).

What is Energy Calculator?

Computes kinetic energy of motion ($E_k = \frac{1}{2}mv^2$) or potential energy stored within a gravitational field ($E_p = mgh$).

How to Use This Calculator

  1. Enter mass in kilograms.
  2. Enter velocity in meters per second.
  3. View energy in Joules, kilocalories, and kWh.

The Mathematical Formula & Variables

Kinetic Energy = 0.5 * Mass * Velocity^2

Step-by-Step Worked Example

Scenario: 64 kg runner moving at 10 m/s (approx 22.4 mph).

  1. Ek = 0.5 * 64 * 10^2 = 32 * 100 = 3,200 Joules.

Result: 3,200 Joules
