Physics 2020 JAMB Past Questions - Question 18: when the brakes in a car are applied, the frinctional force on the tyres is

Correct Answer

D

Explanation

When the brakes in a car are applied, the frictional force on the tires increases, which helps to slow down the car. This frictional force is generated between the brake pads and the brake discs (or drums) and is transmitted to the tires, causing them to slow down and eventually stop the car.

When the brakes in a car are applied, the frictional force on the tires increases. This frictional force is responsible for slowing down and stopping the car. The brake system of a car typically involves friction between brake pads and the brake discs (or drums). When you press the brake pedal, it activates the brake system, and the resulting friction between the brake components generates a force that opposes the motion of the tires, eventually bringing the car to a stop. The frictional force is crucial for converting the kinetic energy of the moving vehicle into heat energy through the process of braking.
