Question

the angle between force and displacement in case of positive work done and negative work done​

Answer 1

Answer:

thus work done by the applied force which is lifting up the body is positive since the angle between the applied force and displacement is positive. Thus work done is negative when 90o < θ <= 180o as Cos θ is negative. ... The angle between the frictional force and the displacement of the body will be 180o

hopes its helpful

Answer 2

Explanation:

In case positive work, Angle : less than 90°

in case of negative work, Angle : Greater than 90°
