Final answer:
The subject of this question is Physics. In Physics, we study the brakes of a car and how they affect the car's motion.
Step-by-step explanation:
The subject of this question is Physics. In Physics, we study the brakes of a car and how they affect the car's motion.
When the brakes of a car are applied, they create a friction force that opposes the car's motion. This friction force slows down the car by exerting a backward force on it.
The rate at which the car slows down is determined by the braking force and the mass of the car. If the braking force is greater, the car will slow down faster. Similarly, if the mass of the car is greater, it will take more time for the car to come to a stop.
