Revealed: the tremendous heat created and energy 'lost' when cars brake.
- Car brakes convert kinetic energy into heat energy.
- When you press the car brake pad a system of levers and pistons multiplies the size of the force on the tires.
- Car brake pads can reach temperatures between 200 and 300 degrees.
- Car brakes are a massive waste of energy.
Car brakes are essential for decelerating quickly, but they're a massive waste of energy.
Car brakes work by converting energy from one form into another from kinetic energy in the speeding car, to thermal, or heat, energy.
Kinetic energy = energy of motion
When you press on the brake pad the force is ...
