We know that the formula for Work Done by an constant force is
W.D = Force x displacement x (cosine of angle between force and displacement).
Situation: A mass m travels 10 meters towards +ve axis and 6 meters back towards -ve axis. Given that coefficient of kinetic friction is 0.1.find W.D by kinetic friction?
But while calculating W.D for friction we use distance covered instead of displacement is it because friction force is a non-conservative force.
If yes does that means For every constant conservative force we use W.D = F.ds.cos and for every constant non conservative force we use W.D = f.distance.cos
