Using the principle of stationary action, we show how spatial translation symmetry leads to momentum conservation, and time translation symmetry leads to energy conservation, as formalised by Noether’s theorem. 📚 Resources and References Symmetries and Conservation Laws: Consequences of Noether’s Theorem American Journal of Physics, 72(4), 428–435 (2004) From Conservation of Energy to the Principle of Least Action: A Story Line American Journal of Physics, 72(4), 514–521 (2004) Deriving Lagrange’s Equations Using Elementary Calculus American Journal of Physics, 72(4), 510–513 (2004) Invariant Variation Problems (Original Noether Paper) Nachrichten von der Gesellschaft der Wissenschaften zu Göttingen, Mathematisch-Physikalische Klasse (1918), 235–257 The Feynman Lectures on Physics Addison-Wesley The Character of Physical Law MIT Press / Penguin Books 🤝 Support the channel Patreon →   / physicsexplained   🔗 Follow me Instagram →   / physics_explained_ig   X (Twitter) →   / physicsexplain1
