Galilean Frame Transforms
For classical (Galileo-Newtonian) mechanics, the transformation law from one inertial or accelerating (including rotation) frame (reference frame traveling at constant velocity - including zero) to another is the Galilean transform.
Unprimed quantities refer to position, velocity and acceleration in one frame F; primed quantities refer to position, velocity and acceleration in another frame F' moving at translational velocity V or angular velocity Ω relative to F. Conversely F moves at velocity (—V or —Ω) relative to F'. The situation is similar for relative accelerations.
| Motion of entities | Inertial frames | Accelerating frames |
|---|---|---|
| Translation
V = Constant relative velocity between two inertial frames F and F'. |

Relative accelerations Apparent/fictitious forces |
| Rotation
Ω = Constant relative angular velocity between two frames F and F'. |

Famous quotes containing the words galilean, frame and/or transforms:
“Last came, and last did go,
The pilot of the Galilean lake.”
—John Milton (1608–1674)
“Candor is a proof of both a just frame of mind, and of a good tone of breeding. It is a quality that belongs equally to the honest man and to the gentleman.”
—James Fenimore Cooper (1789–1851)
“Now, since our condition accommodates things to itself, and transforms them according to itself, we no longer know things in their reality; for nothing comes to us that is not altered and falsified by our Senses. When the compass, the square, and the rule are untrue, all the calculations drawn from them, all the buildings erected by their measure, are of necessity also defective and out of plumb. The uncertainty of our senses renders uncertain everything that they produce.”
—Michel de Montaigne (1533–1592)
