Question

Work done by the force can be *

1 point

positive

negative

positive and negative

Neutral

​

Answer 1

Explanation:

Whenever the force and displacement vector are parallel to each other, the work done on an object is positive which causes the speed and kinetic energy of the object to increase. If the force and displacement vectors are perpendicular, no work is done and the object's kinetic energy remains constant.

Answer 2

Answer:

The work that is done can be positive work or negative work depending on whether the force doing the work is directed opposite the object's motion or in the same direction as the object's motion. If the force and the displacement are in the same direction, then positive work is done on the object.
