In a room with no windows, Zephyr and Kael are standing with their backs against a door to keep it closed because the wind outside is very strong. Suddenly, the wind stops. What happens next to Zephyr, Kael, and the door? Respond very briefly.
When the wind stops, the force that Zephyr and Kael are countering by pushing against the door also stops. Since they are no longer needing to balance any external force, they will unintentionally push the door open, unless they quickly realize the change in pressure and adjust their effort. If they continue to push with the same force they used to counteract the wind, they may stumble into the room as the resistance they were leaning against is gone. The door will swing open more easily than before, assuming it opens into the room where Zephyr and Kael are standing.
