What kind of energy transformation occurs during regenerative braking?

During regenerative braking, kinetic energy is transformed into electrical energy. When a vehicle, such as an electric or hybrid train, slows down, the momentum which is primarily kinetic energy is harnessed instead of being lost as heat, which would typically occur in conventional braking systems. This process converts the kinetic energy produced by the vehicle's movement into electrical energy, which can then be stored in batteries or fed back into the energy supply system.

This transformation is significant because it increases the overall efficiency of the vehicle. By capturing energy that would usually be wasted during braking, regenerative braking not only improves energy efficiency but also extends the operational range of electric vehicles by allowing them to recharge in motion.
