In physics, work refers to the product of force and distance vectors
^{[1]}.

*W* = F · d

Or:

*W* = F d Cosθ

Where θ is the angle that separates the vectors.

Work is a transfer of energy; if *W* is positive, there is a transfer of energy *to* the system, and if *W* is negative there is a transfer of energy *from* the system.

Its units are that of force multiplied by distance, in SI this is Newton · Meter, or Joule
