Work is regarded as positive or negative wrt direction of force... Work done product of displacement in direction of force... For sign, we need to just see the x and y axes for positive and negative work.
Expression: WD= -f.s(costheta)
Hope you are clear with this... Mark as Brainliest if it's appropriate
