Question

Which of these statements is true about brakes?

1) The heavier a vehicle or faster its moving, the more heat the brakes have to absorb to stop it
2) Brakes have more stopping power when they get very hot
3) Brake drums cool very quickly when the vehicle is moving fast
4) All of the above are true

Answer 1

The correct statement about brakes is that the heavier a vehicle or faster its moving, the more heat the brakes have to absorb to stop it.

Step-by-step explanation:

The correct statement about brakes is: The heavier a vehicle or faster its moving, the more heat the brakes have to absorb to stop it.

When a car applies brakes to bring it to rest, the brakes use friction to reduce speed and transform motion energy into heat energy. As a result, the brakes can become very hot after bringing the car to a stop.

Therefore, statement 1) The heavier a vehicle or faster its moving, the more heat the brakes have to absorb to stop it is true about brakes.
