Answer 1

Answer:

B. less than mg

Explanation:

A person's weight changes as he rides an elevator at a constant velocity. If the elevator is moving downward, the person's weight becomes lesser. He is considered to be in "free fall" due to gravity. However, the opposite happens when the elevator goes upward. The person will feel heavier because he is going against gravity. This means his weight is more than his actual weight. If the person will stand on an elevator that doesn't move, his weight will just be the same. All of these is due to Newton's Second Law of Motion where an object's acceleration relies on its force and mass.
