A boy was riding his bike on a level road. He stopped pedaling and applied the brakes. When he applied the brakes, the brake
pads squeezed the wheel, and the bike slowed down and stopped. After the bike stopped, the brake pads had more thermal energy. Why did the thermal energy
of the brake pads increase?
Because some of the motion energy (kinetic energy) that the bike and the boy had was converted into thermal energy of the brake pads
Because the energy that was stored inside of the brake pads was released in the form of thermal energy when the bike stopped
Because some of the thermal energy that the boy had was converted into thermal energy of the brake pads
|D.||Because new energy was made in the form of thermal energy in the brake pads|
