Friction
Friction is force exerted by a surface as something moves across it.There are at least two types of friction, sliding and static friction. For example, as you slide your dogs toy across the surface of your floor, then the floor exerts a frictional force in the opposite direction of the toys motion. There is also friction when you pet a puppy's fur.
