Braking & Energy

danger of skidding!

As you may know from our work on kinetic energy, the faster an object is moving, the more kinetic energy it has. To stop a car from moving we need to apply a force to transfer its kinetic energy into other forms - such as heat.

This is what brakes do - they apply a force in the opposite direction to the motion of the car. This causes deceleration and eventually the car stops.
