We know that work is the dot product between force and displacement .. so dot product always gives scalar (horizontal projection etc) hence work is a scalar quantity?
I want the reason behind it...
we always do work in specific direction..
suppose a man in appliying force at the angle of 30 in the horizontal distance to cover displacement of 3m... hence he is doing work in the direction of displacement..
clearly stated from this example that work always has direction.. then
why it is scalar quantity ? in its actual sense..
