when you apply the brakes of a car its kinetic energy or energy of motion decreases.
a)to what form of energy is the kinetic energy converted?
b)where does the resulting energy end up?
Do the brake drums on the wheels heat up?
so does it convert into heat energy?and the resulting energy is used to heat the brake drums up?
(b) Eventually, the car's kinetic energy is transfered as heat from the brakes to the environment, as the brakes cool down again.
(a) When the brakes of a car are applied, the kinetic energy is converted into various forms of energy. One of the primary conversions is into thermal energy, or heat energy. Friction is created between the brake pads and the brake drums or discs, which converts the kinetic energy into thermal energy due to the resistance of the moving parts against each other.
(b) The resulting energy, in the form of heat, is dispersed into the surrounding environment. As the brakes heat up, this energy is dissipated into the air, or sometimes absorbed by other parts of the car, such as the brake drums. The brake drums do heat up as a result of the energy transfer occurring during braking. However, it is important to note that the brake drums are designed to handle and dissipate this heat efficiently to prevent overheating or damage to the braking system.
