When a driver applies brakes to keep a car going downhill at constant speed and constant kinetic energy, the potential energy of the car decreases. Where does this energy go? Where does most of it appear in a hybrid vehicle?

• Physics -

This energy is lost to friction when the brakes are slowing the vehicle. In normal cars, this energy is eventually converted to thermal energy. However, in hybrid vehicles, when the car is coasting (no gas) the axis is connected to the battery, slowing the car and recharging the battery.

The potential energy transforms into other forms of energy such as thermal energy when the tires are rubbing against the ground.
