If the force is being exerted at an angle th to the displacement the work done is W fd cos th. A newton-meter is the same thing as a joule so the units for work are the same as those for energy joules. The work function or workfunction is defined as the minimum amount of thermodynamic work ie.
Distance is typically measured in meters.
The symbol for work function is F uppercase Phi of the Greek alphabet. What is definition and formula of Mechanical Power. This definition is consistent with the proper definition because a constant force integrates to merely the product of the force and distance. W F s cos th displaystyle WFscos theta Work is a scalar quantity so it has only magnitude and no direction.
