If we drop a rubber ball, it falls down rather than flying up. But more specifically: if we drop the same ball from the same height over and over again, we know it will hit the ground with the same speed every time (within vagaries of air currents). 2018-06-26 Last edited at 23:24, 28 June 2011 (UTC).

2015-06-18 2016-06-14 Noether states that any continuous symmetry corresponds to a conserved quantity (Noether’s current). Noether’s argument is very easily confused with those leading up to the Classical equation of motion (EOM) (least action/variation principle). [Undergraduate Level] - In this video I state of Noether's theorem and discuss symmetries in general. The only prerequisite is Lagrangian Mechanics.

In such systems, there exist local and global conservation laws analogous to current and charge conservation in electrodynamics. The analogs of the charges can be used to generate the symmetry transformation, from which they Noether’s Theorem 7.1 Continuous Symmetry Implies Conserved Charges Consider a particle moving in two dimensions under the influence of an external potential U(r). The potential is a function only of the magnitude of the vector r.
