classical mechanics - Definition of Cyclic Coordinates - Physics …
WEBMay 11, 2021 · Definition. A coordinate qj q j is cyclic if the Lagrangian L L doesn't depend on it: ∂L ∂qj = 0 ∂ L ∂ q j = 0. The corresponding momentum pj = ∂L ∂q˙j p j = ∂ L ∂ q ˙ j is not necessarily conserved unless the Lagrange equations is of the form of the Euler-Lagrange equations, cf. e.g. my Phys.SE answer here.

Trouble with classical mechanics self-learning (How to avoid going …
WEBIt turns out that only classical mechanics is the most difficult part of physics to learn on ones own. I had a friend who confirmed this by comparing how difficult it is to learn classical mechanics (including Lagrangian and Hamiltonian formulation) on his own with electrodynamics and general relativity.
Differences between classical, analytical, rational and theoretical ...
WEBClassical Mechanics is used in two different contexts: First, it is the antonym to Quantum Mechanics. As such, we usually assume a strictly deterministic world ruled by certain differential equations (in one of the many formulations of classical mechanics, see below), as opposed to a quantum mechanical view where probability densities evolve ...
quantum mechanics - Does spin really have no classical analogue ...
WEBNov 17, 2020 · 38. It is often stated that the property of spin is purely quantum mechanical and that there is no classical analog. To my mind, I would assume that this means that the classical ℏ → 0 limit vanishes for any spin-observable. However, I have been learning about spin coherent states recently (quantum states with minimum uncertainty), which do ...
Which classical mechanics book has better content? - Physics …
WEBMay 22, 2017 · 1. Classical Mechanics 3rd Edition by Goldstein, Poole, Safko (They say that this is the golden standard of all the classical mech books) 2. Classical Mechanics 2nd Edition by Herbert Goldstein (I've heard that a chapter from the second edition was removed in the 3rd edition plus it's cheaper) 3.
classical mechanics - What are holonomic and non-holonomic …
WEBJun 4, 2018 · These are called holonomic constraints: f(qi, t) = 0. The cool thing about them is that they reduce the degrees of freedom of the system. If you have s constraints, you end up with n′ = 3N − s <n degrees of freedom. An example of a holonomic constraint can be seen in a mathematical pendulum.
What is an effective potential in classical mechanics?
WEB$\begingroup$ This is very context dependent as there are a lot of times when an effective potential is useful. . Usually one introduces an effective potential when a physical effect whose origin is not a potential can be described adequately as if it simply gave rise to a potential (at least in some variables in some regime of parameter spa
classical mechanics - Any good resources for Lagrangian and …
WEBTaylor's Classical Mechanics. This is the canonical book for undergraduate classical mechanics. It is used almost everywhere in the US for their junior-level undergraduate classical mechanics class, as it's clear, has lots of good problems, and doesn't take mathematical background for granted. It is a great book for a starting course in the ...
What's the standard "roadmap" to learning quantum physics?
WEBI think the usual way as they take it at a university is pretty much the time efficient way to go. The math and$\ $ *at least*$\ $ Classical Mechanics will be necessary. Nobel Laureate Gerard 't Hooft at one put together a selection of introductions in a roadmap style $$\text{click}$$ The navigation system on that site doesn't work for me anymore.
