As w=F.ds

w=Fds cosФ,Ф is angle b/w force and displacement.

W=Fs

Work is a scalar quantity, as it doesn't have any direction but only possesses magnitude. Also, according to a mathematical property, the product of 2 vectors (here force and displacement) is always scalar. VECTOR- A quantity with both, magnitude and direction.

Example: If we push a stone, we apply a force to do so and we say that we apply force to the east (e.g.) and if there is a displacement produced, then we say, it is produced in the eastern direction. But, on the other hand, we never say that work is done towards the east.
