My grad school was basically working through F=Ma-Cv-Kx in all it's expanding varied glory, working up to full blown finite element analysis.
Ultimately it all comes down to choosing the most convenient basis functions for the questions you're answering.

- denotational 3y agoF is a forcing function, not the resultant force. It’s often arranged this way with all the derivatives on one side (as opposed to having the resultant force, ma, on one side of the equality by itself) so that it matches the general form of a non-homogeneous second-order linear differential equation. (At least I assume this is what the original commenter meant!).
- JadeNB 3y agoAh, that makes more sense. Thanks!
