Translation (physics)

In physics, a translation is the operation changing the positions of all objects according to the formula

(x,y,z) \to (x+\Delta x,y+\Delta y, z+\Delta z)

where xyz) is a constant vector. Such an operation can be generalized to other coordinates, for example the time coordinate.

Because of Noether's theorem, the translational symmetry is equivalent to momentum conservation.
