Final answer:
A vertical force does indeed do work on an object when the object is moving in the vertical direction and the force and displacement are in the same direction.
Step-by-step explanation:
True or False: Does a vertical force do work on an object that is moving in the vertical direction? The answer is True. According to the definition of work in physics, work is done on an object when a force causes a displacement of the object in the direction of the force. If an object is moving vertically and there is a vertical force acting on it, this force is doing work as long as the force and displacement are in the same direction, which means that the force contributes to the object's movement.
