reference frame
Coordinate system basis
A reference frame is a coordinate system or set of axes used to measure position, motion, and other physical properties.
In physics, the same event looks different depending on your reference frame—a passenger on a train sees a dropped ball fall straight down, while someone on the platform sees it arc forward.
Einstein's relativity hinges on how physical laws behave across different reference frames.
The concept extends beyond physics: From my reference frame as a teacher, the policy makes no sense.
