A 180-pound person takes a ride in the elevator that goes up the side of the Space Needle in Seattle. Much to the amusement of the other passengers, this person stands on a bathroom scale during the ride. During the time the elevator is accelerating upward, is the reading on the scale greater than, equal to, or less than 180 pounds? Explain.
