2) Negative work- When the force and the displacement are in the opposite direction(theta=180 degrees)

3) Zero work- When the applied force does not cause displacement(theta=90 degrees)

Answer 2

Answer:

1. Positive work- when the force and the displacement are in the same direction(theta=0 degrees)
2. Negative work- When the force and the displacement are in the opposite direction(theta=180 degrees)
