Answer 1

Remember the last time you were on a see-saw? Did you notice it takes more effort to push yourself up, and a smaller distance, when you were sitting closer to the middle of the see-saw? But if you sit on the very end it’s very easy and you can jump really high with less effort. A door is very similar to a see-saw and the door hinge is like the middle of the see-saw where it rotates.
