Automover Brake ControllerA brake is a device for slowing
or even stopping the motion of a machine, and to keep it from starting
to move again. The kinetic energy misplaced by
the moving part is usually translated to heat by friction. Alternatively,
in regenerative braking, much of the energy is recovered and stored
in a flywheel, capacitor or twisted into alternating
current by an alternator, then rectified and stored in a series
for later use.
Note that kinetic energy increases with the square of the velocity (E = ½m•v2 relationship). This means that if the speed of a motor vehicle doubles, it has four times much energy. The brakes must therefore dispel four times much energy to stop it and consequently the braking distance is four times longer. Brakes of some description are fitted to most wheeled vehicles, including automobiles of all kinds, trucks, trains, motorcycles, and bicycles. Baggage and shopping carts may have them for use on a touching ramp. Some aero planes are fitted with helm brakes on the undercarriage. Some aircraft also feature air brakes intended to slow them down in flight. Notable examples include gliders and some WWII-era fighter airplane which allow the aircraft to maintain a safe speed in a steep descent. Most modern cars have void assisted servo brakes.
