Answer 1

Think of it like playing on a teeter totter. If you’re closer to the center, you can’t really lift your friend up unless you jump really hard or maybe you’re the biggest kid around and can do it because you weigh more. Opening the door closer to the hinge is like sitting closer to the center of a teeter totter.
