I would like to understand Noether's Theorem.
Every layman's explanation of this theorem states that momentum
conservation results from
symmetry under translation. That is to say, momentum is constant as an
object moves.
But these descriptions don't discuss the exchange of momentum between
objects. That is what I would like to see follow from Noether's
Theorem. Perhaps someone can suggest a better
explanation of how Noether's Theorem demonstrates conservation of
momentum under exchange?
