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 position Relative velocity |
Relative accelerations Apparent/fictitious forces |
| Rotation
Ω = Constant relative angular velocity between two frames F and F'. |
Relative angular position Relative velocity |
Relative accelerations Apparent/fictitious torques |
| Transformation of any vector T to a rotating frame |

Famous quotes containing the words galilean, frame and/or transforms:
“The Galilean is not a favourite of mine. So far from owing him any thanks for his favour, I cannot avoid confessing that I owe a secret grudge to his carpentership.”
—Percy Bysshe Shelley (1792–1822)
“With its frame of shaking curls all in disarray,
earrings swinging,
make-up smudged by beads of sweat,
eyes languid at the end of lovemaking,
may the face of the slim girl
who’s riding on top of you
protect you long.
What’s the use
of Vi.s».n»u, iva, Skanda,
and all those other gods?”
—Amaru (c. seventh century A.D.)
“It is old age, rather than death, that is to be contrasted with life. Old age is life’s parody, whereas death transforms life into a destiny: in a way it preserves it by giving it the absolute dimension. ... Death does away with time.”
—Simone De Beauvoir (1908–1986)
