Real World Examples
Sprinting Human
A 70kg person running at 5 m/s has 875 Joules of kinetic energy.
Driving Car
A 1500kg car at 30 m/s (67 mph) has 675,000 Joules.
# About This Calculator
Kinetic Energy is the energy an object possesses because of its motion. It depends on both the mass of the object and the square of its speed.
Because of the v² term, doubling the speed of an object increases its kinetic energy by a factor of four. This is why high-speed collisions are significantly more destructive than low-speed ones.
How To Use
- Enter the **Mass** of the object in kilograms.
- Enter the **Velocity** (speed) in meters per second.
- The result is provided in **Joules**, **Calories**, and **Watt-Hours**.
