Work = force × displacement
I think ......
force & displacement are vector quantity. so
product of force & displacement is the product of two vectors.
product of two vectors is a scalar quantity .
:-)hope it helps u.

Work = force *displacement.
Force is the action created in one direction.Displacement is that action after applying force means it's effect of force. We don't know where and when that event happen, we only know it is happen in this universe. For, this information, we mark work as scalar because force and displacement need space and time to occur, without space, nothing move and also without time, we cannot calculate exact relation. As force and displacement interact, we call it work, if one cannot is zero, then work is also zero, because one can not exist in space and time
