Contradiction between Lagrangian and Hamiltonian formalism
I am currently studying an introductory course to theoretical physics. I stumbled upon something I can't seem to understand, namely:
Suppose that we have a system without any potential energy, and thu …

Particles connected with spring, sliding over lines. Question about the potential energy
I'm currently studying small oscillations with the Lagrangian formalism. I stumbled upon an exercise that I can't seem to understand the method of solving it.
Two particles $P_1$ and $P_2$, with the …

Arguments of specific Hamiltonian, always conserved?
I'm studying an introductory course in theoretical physics, I stumbled upon something I really can't understand.
So, in my book there is written the following statment:
Consider a Hamiltonian system …
