If a piece of fabric was stretched out, and I pushed my finger into the fabric with a force of 5N, the fabric will push back the 5N because of its potential energy. correct?
So what if I did the the same thing and pushed my finger agaist a wall? The wall doesn't stretch but it still pushs back with 5N. How does it know to puch back 5N on my finger?
