Final answer:
When coming to a stop in a manual shift vehicle, it is necessary to let up slightly on the brake pedal to prevent the car from stopping with a jer`k. This can be explained in terms of the relationship between static and kinetic friction.
Step-by-step explanation:This can be explained in terms of the relationship between static and kinetic friction.
Static friction is the force that prevents an object from moving when a force is applied to it. This is the friction between the brake pads and the wheels when the brakes are applied. Kinetic friction, on the other hand, is the force of friction between two surfaces in motion relative to each other. As the car slows down, the wheels are still rotating but at a slower speed. When the brake pedal is released suddenly, the wheels and brake pads momentarily sti`ck together due to static friction. When the brake pedal is released slowly, the wheels and brake pads can separate gradually, reducing the abrupt je`rking motion.
