Hello all. I have a doubt about the work done by friction force on a wheels , in two diferent situations: a) In Morin's mechanics book, chapter 5 (page 146) he considers the situation in which a car is braking without skidding. He claims that the friction from the ground on the tires causes...

When a car moves forward, the wheel turns it exerts a force on the road in the opposite direction of travel, and friction counter acts it. the wheel turns and the car moves forward This implies that friction on the wheel is acting in the direction of the car moving. Though I thought that...

Suppose we have an inclined plane and 2 wheels. Both wheels have the same mass M but different radius R. So the only difference is that one is bigger than another. We put both wheels on the top of the inclined plane. They are in the same position, and then we let them go. I know that the wheel...
