Final answer:

Explains the relationship between static and kinetic friction in braking to prevent sudden stops and ensure smoother deceleration.


Explanation:

Static friction refers to the force that opposes the initial motion of an object at rest, such as when the brake pedal is initially pressed. When the brakes are applied, kinetic friction comes into play as the brake pads and rotor interact to slow down the car. Releasing the brake slightly allows the transition from static to kinetic friction, preventing a sudden stop and ensuring a smoother deceleration.
