If an object undergoes displacement while being acted upon
by a force (or several forces), it is said that work is being
done on the object. If the object is moving in a straight line
and the displacement and the force are known, the work
done by the force can be calculated as
W = Fs cos 0,
where W is the work done by force F on the object that
undergoes displacement s directed at angle relative to F.
Note that depending on the value of cos 8, the work done.
can be positive, negative, or zero.

If an object undergoes displacement while being acted upon

done on the object. If the object is moving in a straight line
and the displacement and the force are known, the work
done by the force can be calculated as
