In my bedroom the window is almost parallel to the door. Imagine where the door knob is being a limbo stick directly across. And there is the window. When it is open the door always slams, even pushing it lightly. When its closed it just shuts normally. Why do you think this is?

i think this happens because the air is basically causing a vacuum in the room, therefor pulling air in and out, causing the door to shut or open.

It's all about pressure. With the window closed, as the door shuts, the air pressure in the room becomes slightly elevated (because the shutting door is decreasing the volume of the room). This elevated pressure acts as a force trying to prevent the door from shutting.
When the window is open, the air in the room has somewhere to go as the door closes on it, and so there is no pressure elevation, and no force opposing the closing of the door.

some issues. The door seal as already reported. attempt some spray silicone around the finished door seal. yet another may well be a heavy sheet of plastic ( 5 mil ) or so, that is between the door panel and the door. this might have been got rid of or has an air hollow. If a wedge grow for use on the door to alllow get admission to because of the fact of a lockout. a area of interest may well be recent on the backside of the window permitting air in besides. each each now and then hyper-extending that seam creates a area of interest. that's what comprises strategies first. desire this enables...

I think your room is airtight and when the door closes it is slowed by the air having to get out of its way for it to close. With the window open the air moves out rapidly and the door slams fast.

The air is able to move better when the window is open, so your door can be closed easier, seeming to slam, but really it just needs less force to close it since the air molecules are moving easier.

The wind blowing by the window causes pressure in the room to be lower than the rest of the house.

Humidity can cause this to occur, depending on where you live. Otherwise, a normal vacuum effect is more than likely the reason this happens. Hope this helped. Good luck and take care!

this is no doubt caused by the increase or decrease in air pressure when the window is opened or closed.

Wind draft.
