why work has only magnitude and not direction because if we see the formula W =F ×s...and force and distance has both direction amd magnitude so why work has only direction....

Heya user !!!
Here's the answer you are looking for
Work is the dot product of F and s.
Dot product of 2 vectors give rise to a scalar quantity which has no direction but only magnitude.
If a and b are 2 vectors then their dot product is,
where alpha is the angle between the 2 vectors.
Since W is a dot product of 2 vectors F and s, it is scalar and has only magnitude.
That's why, we write,
W = F.s = FscosA, where A is the angle between F and s vector.

harsh282:
it is nice answer but it is not of my level becuse in my book there is not any dot product and cos etc...so thxx
ohh!!
hahha
I beg your pardon
:(
its okk ur i think ur answer is right
:-)
yess
