Hi.
Force was introduced to me as "what a force meter in an inertial frame measures". I'm a bit confused about the interpretation of Newton's second law$$F=\frac{dp}{dt}\enspace.$$
Is it a definition? Is it an empirical finding? Can it be derived theoretically?
Or do we need to make the "definition" "what a force meter in an inertial frame measures" more rigorous? How could we formulate this more mathematically?
