Brakes absorb more ______ to stop heavier or faster vehicles?

Explanation:
Brakes work by turning the vehicle’s kinetic energy into heat through friction between the brake pads and rotors. When a vehicle is heavier or moving faster, it has more kinetic energy that must be shed to stop, so more energy is transformed into thermal energy. That means the brakes heat up more as they absorb this energy. The heat is the key form of energy being absorbed during braking. While friction is the mechanism that makes braking possible, the energy isn’t absorbed as sound or wind; those aren’t the primary forms of energy transfer in braking.
