Classical Mechanics
In the Newtonian limit where approximately the Galilean transformation
holds, it is identical with the vector difference between the velocities of A and B, as evaluated in terms of a single coordinate system:
- .
Due to Einstein's Special Relativity (SR), doesn't hold in general. The expression "the velocity of A relative to B" is shorthand for "the velocity of A in the coordinate system where B is always at rest".

Famous quotes containing the words classical and/or mechanics:
“Against classical philosophy: thinking about eternity or the immensity of the universe does not lessen my unhappiness.”
—Mason Cooley (b. 1927)
“It is only the impossible that is possible for God. He has given over the possible to the mechanics of matter and the autonomy of his creatures.”
—Simone Weil (19091943)
