If you're interested, Landau & Lifschitz "Vol 1: Mechanics" has a derivation of classical mechanics from purely physical arguments, from first principles. F=ma is on page 9.
- acqq 7y agoAnd that derivation seems to be known at least since 1788: https://en.wikipedia.org/wiki/Lagrangian_mechanics https://en.wikipedia.org/wiki/Lagrangian_mechanics
- andrepd 7y agoYes, but Landau derives that in a supremely elegant way, from purely physical arguments.
- acqq 7y agoI personally always prefer first historical approach, only then elegant summaries. I am aware that some like just a distilled material. Still thanks for mentioning Landau and Lifschitz book!
