As you walk down the stairs, you apply a force to keep yourself from falling down the stairs. The force is in the upward direction, but your movement is in the downward direction. If the force is in the opposite direction of motion, work done by the force is negative. Gravitational force, because it pulls down, does positive work.
Your up stairs t-stat should be 2 degrees cooler than down stairs ,due to heat rise.
across Good way to remember it, along the corridor then up the stairs.
There are many components to a winding staircase.First know that your inside and outside radius will rise at different angles because your run changes(pie shaped treads)If you need some direction I will need some more info.
Stairs have no power at all. They simply make it possible for you to direct your own power in a direction that will accomplish a certain result when you use them. Elevators use electrical power and deliver it in a mechanical form for your use.
Through the day, the heat will expand, or retract the wood in the stairs. At nightfall, the stairs cool off, and will find their original position, which will snap and creak every now and then. A lot of sounds around the house, are due to temperature changes. Wooden floors, roofing, etc. I hope I helped
Based on chemical properties exothermic phase changes are those that release energy. The exothermic phase changes are gas--> liquid, liquid --> solid, and gas--> solid. Looking at a phase diagram if you are going up the "stairs" the conversions require energy going down the "stairs" energy is released.

You do it by exerting a force greater than the gravitational force, in the opposite direction ... a lot like what you do with your legs when you want to climb some stairs.
