Question

A person driving a car applies the brakes. This produces friction, which stops the car. Into which type of energy is the mechanical energy of the car converted?

Answer 1

A mechanical brake applies a friction force to convert the kinetic energy of the vehicle into thermal energy which then dissipates into the atmosphere. As with any system, the process of braking must follow the principle of conservation of energy

Answer 2

A mechanical brake applies a friction force to convert the kinetic energy of the vehicle into thermal energy which then dissipates into the atmosphere. As with any system, the process of braking must follow the principle of conservation of energy.
