Some fairly big changes.
''W'' = F · d
''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.
