Friction helps in increasing gas mileage.?

Question

A. True

B. False

Answer 1

If there was a frictionless surface, the wheels on the car would just spin, and the car would not go anywhere, but a single push could move the car an infinite distance.

In reality, it is good for roads to have a large amount of friction, so that the tires can grip onto the road so that all of their rotational energy can be used to push the car forward.

On the other hand, friction will reduce your speed if you are going down a hill.

Meanwhile, breaks use friction to reduce the speed of the car.

However, friction in certain other parts of the car would be bad.

Answer 2

B. False

Answer 3

FALSE  The number one reason for poor gas mileage is using your brakes.

Answer 4

False

Friction almost always represents unwanted losses, therefore losses in efficiency

Of course, if your tires had zero friction with the road, you would get some pretty poor mileage, so you can always twist a question like this around
