Friction is a force that slows moving things down and turns the moving energy into heat energy. When two things rub together, like your bike tires and the road, friction between them slows you down. Thereโs also friction in the metal parts of the wheelโs hub โ at the center. Thereโs even friction between the fibers and rubber of the tires themselves as they flex and roll. Thatโs why you eventually stop rolling when you stop pedaling. Rough things make more friction than smooth things. Rubber shoes on a clean wooden basketball floor create more friction than do hard metal skate blades on smooth ice.
