Tell me if this theory of mine makes sense.
The stairs in my house creak. Creaking is caused when you step on stairs.
It makes sense to me that it should be quieter to run up and down my stairs, that they should creak less.
Here is the reason.
When you walk up stairs usually, you push all your weight up with one foot, and then rest all your weight on another step. All your weight gets pushed down on the stair, which in repsonse, creaks. If you run up, and get a good push off of the ground, you start out with upward inertia. It takes less of a push-off from any individual step to get to the next one, since you've already got upwards inertia.
With running down the stairs, again, you're not fully coming to a rest on any stair. If I'm only touching a stair long enough to kind of guide myself down, it seems that I'm not putting all the force my body has to offer onto that stair, and again, I'd push down on it less, and it should make less noise.
I think this works. My mom doesn't. I think it's just cause she associates running with noise in her head, and even though walking slowly would cause lots of slow creaks, the rapid-fire minute creeks combined with seeing me go up the stairs quick puts her in an unusual frame of mind, like running inherently causes disruptions.
In theory at least, is my idea correct?
Thanks,
Jacob
