Mechanical Work

See the calculation of work done moving an object. Work is equal to the force exerted on an object in the direction of motion times the displacement . The force is the projection on the axis of a force that makes an angle with the object. No work is performed if the displacement is zero, even when there is a force. Remember that the unit for work is the joule (J), equivalent to a newton-meter.
