Why do doors close easier with a window open?
In: Physics
It’s the wind. Even if you don’t feel it strongly, air is coming in through the window. Most doors are meant to be moved around very easily. Even a tiny push can move a lightweight door on smooth hinges. If the window is across the room from the door, than the farther the door closes, the more of its surface area is facing the open window, and it closes even faster than before. The doors in my home will slam shut if the window is open even when it isn’t windy.
