How Do Ball Bearings Reduce Friction? , Ball bearings reduce friction by using smooth balls lubricated with oil or grease that freely roll between a smooth inner and outer surface. The main concept of the ball bearing is that objects that roll past each other produce less friction than if the objects were sliding against each other.Read more≫

What Does Friction Do? , Friction is a force that tends to stop motion or resist the motion of objects. Friction is always a negative force, which means it acts in a direction opposite to the direction of the force applied to the object. Movement of objects through air and liquids gives rise to friction.Read more≫

Why Is Friction Good? , According How Stuff Works, friction is good because it prevents sliding while walking, it protects vehicles from skidding by slowing them down, and it makes writing possible. Friction occurs when two surfaces come into contact. Excess friction hinders movement, and it wastes energy. Friction refers to a force that opposes motion. It is important because it is applied in almost all life processes.Read more≫
