SUMMARY
In a downward-accelerating elevator, a negative normal force cannot be exerted on the elevator floor by a person. The normal force, which is the upward force exerted by the floor, cannot become negative; if it reaches zero, contact between the person and the floor is lost. This principle is rooted in Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
