Work and Power

Work and Power. Chapter 5. Work. Work is done when a force causes a displacement in the direction of the force W = Fd (force and displacement parallel) Unit is newton x meter = joule (J) If force is at angle to displacement must find component of force in that direction W = Fd(cos q ).
