I have a question that would probably be easy for you.
If we could put an elevator together with its shaft on a scale and have its motor pull it up, lets say for 50 floors. will the reading on the scale be less while the elevator is traveling?
I'm not talking about fluctuations that will be caused by inertia as it's starting to move, I'm talking about the weight while the elevator is being pulled up steadily.
I tend to think that it will stay the same but on the other hand I also think that the motor at the top pulls it up like a force that uses energy that objects gravity and might make the scale read less while it pulls?
Or maybe because it's slow it will weight the same and if it would've been pulled up "as fast as a rocket" the elevator will be "weightless" for a few seconds?
I didn't study physics but I'm curious.
