in order for work to be done, what three things are necessary?

power, a force, and movement in the opposite direction of the applied force

balanced forces, motion, and distance covered over time

unbalanced force, motion in the same direction as the applied force, and power

unbalanced force, motion, and movement in the same direction of the applied force

The correct answer is "unbalanced force, motion, and movement in the same direction of the applied force".

Explanation:

To do work, the applied force on the object should move the object. In this case, the work is said to be done.

The work done can be zero, positive and negative.

If the force is applied to an object but there is no displacement occur then the work done is zero in this case.

If the force is balanced then there is no movement by the applied force.

From the given options, unbalanced force, motion, and movement in the same direction of the applied force are three things necessary for work to be done. In this case, the positive work is done as the direction of the applied force and the direction of the movement are in same direction.
