WebWork done by friction comprises the moving body’s displacement opposite to the direction of friction force. The applied force to the body makes the displacement in its direction. Newton’s third law of motion employs a friction force against the body’s motion as a reaction force. How do you calculate work done by friction? Work done by Friction WebMar 26, 2016 · The equation relates the magnitude of the force of friction to the magnitude of the normal force. The normal force is always directed perpendicular to the surface, and the friction force is always directed parallel to the surface. FF and FN are always perpendicular to each other.
