KE = ½ m v²
Kinetic energy (KE)
144,675.93 J
In other units
Working
Then the variable to solve for.
The energy is shown in joules and many other units.
Kinetic energy grows with the square of speed: doubling speed quadruples the energy, which is why braking distances grow so quickly.
3,600,000 J (3.6 MJ). A food Calorie (kcal) is 4,184 J.
Standard gravity, 9.80665 m/s². Real gravity varies by about ±0.3% across Earth's surface.
