WebFriction. Friction is a force that opposes relative motion between surfaces in contact. One of the simpler characteristics of friction is that it is parallel to the contact surface between surfaces and always in a direction that opposes motion or attempted motion of the systems relative to each other. If two surfaces are in contact and moving ... WebIt is saying that the force due to gravity is a standard gravitation constant g times the mass of the object m, or. F = gm.
