Regenerative braking involves harnessing the energy that is typically lost when a car decelerates and brakes and instead using it to recharge the car's batteries. Unlike traditional braking systems that simply dissipate energy, regenerative braking allows some of that energy to be recycled.
(a) What is the energy conversion process that results in the wastage of energy in a normal car during braking?
(b) How does regenerative braking differ from normal braking in terms of energy conversion?
Answer
(a) In a typical car without regenerative braking, when the driver applies the brakes, the car's kinetic energy is converted into heat energy due to friction between brake pads and the wheels. This heat is then dissipated into the atmosphere and cannot be reused.
(b) Regenerative braking converts kinetic energy into electrical energy by running the electric motor in reverse, recharging the car battery.
