there are four general types of friction: static, kinetic, rolling and fluid. friction is defined as the force that resists the motion of two objects sliding against each other.read more≫
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≫
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≫
