Weighing Something in an Elevator

  1. Oct 30, 2010 #1
    If you were to way an object on a Newton spring scale in an elevator, when would the scale display the largest number?

    elevator moving up
    moving down
    no affect

    In my opinion, an acceleration in the elevator would be required, as that would unbalance the forces and was travelling at a constant velocity there would be no affect. I feel as though if anything it would be on the way up rather than down that the scale might read more but this is more a hunch than anything, looking forward to your thoughts!

    You are correct, the problem is not worded correctly
    This is correct, but rather tnan make it a hunch, apply Newton's 2nd law....the net force must be in the direction of the acceleration.
