Why it gets easier to push open a door, the further you are from the hinge?

Answer 1

It takes a set amount of energy to move something, like a door. That energy can be from high effort over a short distance or low effort over a long distance. When you’re further from the hinge, you have to push a few feet compared to a few inches near the hinge.

Energy = force (effort) x distance

Edit: this is true for a set door speed.
