Mechanical Work
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.
