If \(\vec{F}\) and \(\vec{S}\) represent the applied force and displacement of an object, then the work done is
If \(\vec{F}\) and \(\vec{S}\) represent the applied force and displacement of an object, then the work done is
Show Hint
To remember the sign of work:
Same direction (\(0^\circ\)) \(\to\) Positive.
Opposite direction (\(180^\circ\)) \(\to\) Negative.
Perpendicular (\(90^\circ\)) \(\to\) Zero.
Same direction (\(0^\circ\)) \(\to\) Positive.
Opposite direction (\(180^\circ\)) \(\to\) Negative.
Perpendicular (\(90^\circ\)) \(\to\) Zero.

- zero if \(\vec{F}\) and \(\vec{S}\) are in the same direction
- maximum if \(\vec{F}\) and \(\vec{S}\) are at right angles to each other
- the area under the graph between \(\vec{F}\) and \(\vec{S}\)
- positive if the angle between \(\vec{F}\) and \(\vec{S}\) is obtuse
- negative if the angle between \(\vec{F}\) and \(\vec{S}\) is acute
