Analytical Mechanics Go Brrrr

Remember when momentum was just a simple P = mv equation? Those were the days! Now it's evolved into this terrifying multi-dimensional nightmare with partial derivatives and generalized coordinates that would make Newton himself curl up in fetal position.

What you're witnessing is the glow-up (or breakdown) from basic Newtonian mechanics to Lagrangian/Hamiltonian formalism - where momentum gets a fancy makeover with canonical coordinates and enough summation notation to induce spontaneous eye twitching in physics undergrads.

It's like momentum went from "I just started high school" to "I have three PhDs and crippling impostor syndrome" real quick. And yes, I definitely feel ancient now, thanks for asking!
