The passage around this formula
The first, , lives in the nonrelativistic (Galilei) symmetry group: translate the apparatus by a fixed vector , apply a velocity boost to the particle, translate by - , boost by - . As abstract group elements this composes to the identity, because ordinary spatial translations and ordinary Galilean boosts, considered as instantaneous operations with no elapsed time attached, form an abelian subgroup: order does not matter, and the net element is trivial by direct substitution.

A variable is a named place for a value. Its letter is a local label: x can mean position in one formula and a data point in another.
