I understand that we can never be sure that we have a perfect model, I'm more curious about the models that we use that have errors that we are aware of. Something like hooke's law for example. If I'm correct it's an approximate model that we still use. Is that only because it's an old model...

But are our best and most current models only approximate because we don't have perfect knowledge of how things really work, or is it also because we have simplified the models and made them less accurate and more approximate in order for them to be useful? Also, what are some examples of models...

But are there any known simplifications with our current models? Also are there laws or theories that we don't use models to understand?

Must models always be a simplified version of our perception of reality? Bohr's atomic model for example isn't entirely correct. It is only approximately accurate. Are all models simplified and approximate in this way? Is our current model, the quantum mechanical model simplified in this way?

What role do theories, models, and laws play in the scientific process? Is there a clear dividing line between a theory and a law? Are models used in both theories and laws? All theories and laws? Do our best current models perfectly represent reality to the best of our knowledge, or are they a...

If the depth of water increases, and it's speed of a wave in that water also increases as a result, what happens to the frequency and wavelength of that wave? Would the frequency remain the same and the wavelength increase?

How exactly is voltage measured between two points? How can a point have more electrical potential energy than another?

I have a few questions about voltage. Is it always measured between two points, or can it be measured between two objects? What gives an object more electrical potential? Is it just free electrons? Can there be a voltage between two neutrally charged objects? Why does voltage drop occur through...
