Weblubricant. Friction, the rubbing of one object against another, is the worst enemy of machinery. It wears out the metal, wastes power, and generates heat. To reduce friction, substances called lubricants are applied to the bearing surfaces of machinery—that is, the surfaces that rub against each other. The word lubricant comes from the Latin ... WebFriction is a force that resists the sliding or rolling of one surface over another. When a box is pushed across a floor, friction between the floor and the box acts to resist its …
WebFriction is the resistance of motion when one object rubs against another. Anytime two objects rub against each other, they cause friction. Friction works against the motion and acts in the opposite direction. When one … entering a plea agreementWebfriction, force that resists the sliding or rolling of one solid object over another. Frictional forces, such as the traction needed to walk without slipping, may be beneficial, but they also present a great measure of opposition to motion.
