What Is Kinetic Energy?
Kinetic energy is the energy possessed by a moving object. It depends on the object's mass and the square of its speed.
How is it calculated?
How Is It Calculated?
Ek = ½ × m × v²
- Enter the mass (kg) and the speed (m/s).
- Multiply the square of the speed by the mass and 0.5.
Unit: joule (J).
Frequently Asked Questions
How many times does the energy increase when the speed doubles?
Since the speed is squared, when the speed doubles the kinetic energy quadruples.
