WebFriction is the force that acts when one object tries to move or slide over the surface of another object. It can be defined as the resistance of motion when one objects rub against other. Friction works against the motion … WebIntroduction. Friction is a force that opposes motion between any surfaces that are touching. Friction can work for or against us. For example, putting sand on an icy sidewalk increases friction so you are less likely to slip. On the other hand, too much friction between moving parts in a car engine can cause the parts to wear out.
