n. (plural of frame of reference English)
Wikipedia
Frames of Reference is a 1960 educational film by Physical Sciences Study Committee.
The film was made to be shown in high school physics courses. In the film, University of Toronto physics professors Patterson Hume and Donald Ivey explain the distinction between inertial and noninertial frames of reference, while demonstrating these concepts through humorous camera tricks. For example, the film opens with Dr. Hume, who appears to be upside down, accusing Dr. Ivey of being upside down. Only when the pair flip a coin does it become obvious that Dr. Ivey — and the camera — are indeed inverted.
The film's humor serves both to hold students' interest and to demonstrate the concepts being discussed.
