I was studying the physics involving glass and got curious while looking to my window.
The window weights 3kg.
The “ground” which the window would fall is made from wood, the same wood that holds all four sides of the glass like a frame. (common, not tempered glass)
The glass has an area of 0,27 square meters, and has a width of 3mm.
The fall would be straight down, same movement as closing the window, but instead of a supported lowering, it’d be a free fall from it’s stand.
