... The SI unit for work is the joule (j), which equals one Newton • meter (N•m). For maximum work to be done, the object must move in the direction of the force. If the object is moving at an angle to the force, determine the component of the force in the direction of motion (W = FΔd cos θ) . Remember, ...
