Why do doors close so hard when the windows are open?

Even if it’s not windy at all, my door would slam with the slightest push. Does not happen with my windows closed.

With the windows closed the door is creating vacuum or pressure in the room as it gets close to closing, which winds up slowing down the rate at which the door is moving. With them open that doesn’t happen so it closes with full force.
