For this problem I need to figure out how weight changes in a moving elevator. So for example if I had a 20lb dumbbell on a scale and went up 3 floors would the actual weight of the dumbbell change? How would this show on the scale. Then I have the same question except this time the elevator is going down? I really just need the basic concept of how gravity affects the weight. Thanks.
No equations needed, its just a theory problem.
