Re: Comment: "Why do HS teachers insist on teaching what must be unlearned?"
You mean, why teach things we all KNOW are wrong, like F = ma or P = mv? Or why teach that thermal expansion is linear , or that air obeys the ideal gas law? Perhaps because in a wide range of important cases, it gives a useful working approximation that describes the world in which we live.
