let F be the constant force that is acting on the object in the direction of its displacement 's'
then, work done ( W ) = F*s
0
but,in class 9,we dont have it as the problem is not too complex
i.e. no problem in angle is given
so,no need of theeta and it's not in our text.
btw,i think it's in 10th

F.S Cos theeta  = work done when a force is acting on an object in the direction of displacement
