Define Work Done By A Constant Force And Give Some Examples Of It$work=\left(\mathrm{cos}\mathrm{tan}tforce\right).\left(displacement\right)orW=F.S=FS\mathrm{cos}\theta =\left(F\mathrm{cos}\theta \right)S=F\left(S\mathrm{cos}\theta \right)$

The product of the displacement of the object (to which the force is applied) and the component of the constant force that is parallel to the direction of displacement is known as the work done by a constant force. To put it another way, the work done by a constant force is the same as the dot product of force and displacement. $work=\left(\mathrm{cos}\mathrm{tan}tforce\right).\left(displacement\right)orW=F.\to S\to =FS\mathrm{cos}\theta =\left(F\mathrm{cos}\theta \right)S=F\left(S\mathrm{cos}\theta \right)$ where $\theta$ is the angle between F and S
3. In addition to force and displacement, work done also depends upon the angle between force and displacement.
4. If F or S is zero, work done is zero.
5. Also if $F\ne 0,S\ne 0,but\theta =90°$, then $W=FS\mathrm{cos}90°=0\left(\because \mathrm{cos}90=0\right)$
6. An example of work done by a constant force is the work done by a constant force of 2 Newtons on an object having a mass of 3 kilograms.
