When a bicycle rider puts on the brakes, friction causes some of the mechanical energy to be transformed into heat energy. This process is similar to how a car's brakes convert kinetic energy into heat to reduce its speed. During this energy transformation, the brakes can become very warm, indicating the conversion of the bike's motion energy to thermal energy due to the friction between the brake pads and the bike wheel.
When a bicycle rider applies the brakes, friction converts mechanical energy into heat energy. This transformation occurs as the brake pads create resistance against the wheels. The heat results from the friction and can warm up the braking components.
