Translation (physics)
|
|
In physics, a translation is the operation changing the positions of all objects according to the formula
- <math>(x,y,z) \to (x+\Delta x,y+\Delta y, z+\Delta z)<math>
where <math>(\Delta x,\Delta y,\Delta z)<math> 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.
