Braking Energy Summary![]() Brakes reduce the kinetic energy of a moving vehicle. To stop something, the energy removed must equal the work done by the brakes.
Work done braking = kinetic energy removed from vehicle
Using this formula, you can work out the braking distance from initial speed and force, and more!
Kinetic energy increases in direct proportion to the speed-squared. This explains why braking distance increases in an identical way.
