The Energy of Formula 1

Racing cars experience significant energy loss due to braking, where kinetic energy is converted to heat. Modern Formula One cars address this with a Kinetic Energy Recovery System (KERS), which captures and stores energy typically lost as heat. This stored energy can be used for overtaking and high-speed maneuvers, providing an extra 80 horsepower. KERS not only improves energy efficiency but also enhances the excitement of racing by enabling strategic energy use.
