Does work have a direction?
Does Momentum have a direction ?
Work doesn’t have direction; it just can be positive, negative or zero depending upon the angle between the force applied and the direction of the displacement. does this mean that + or - do not indicate a direction ?
A force does positive work on a particle that has a displacement pointing in +ve X-direction. The same force does negative work on a particle that has a displacement pointing in the +ve Y-direction. In which quadrant does force lie? Explain your answer.
