| Abstract | How many vertical jumps does it take to jump off of a rotating merry-go-round (MGR)? The answer is hidden in the expression: "r[subscript n]" = "r[subscript 0]" (1 + ["beta superscript 2") ["superscript n/2"]. When you make a vertical jump on a train moving on a straight line at constant speed (inertial frame), you land on the same spot. Not so on a MGR! A note in "The Physics Teacher" and a recent viewing of a 1960s gem online, "Frames of Reference" by Ivey and Hume, combined to motivate this paper. A very interesting paper by A. E. Wilson describes "Jogging on a Carousel" but does not include a simple vertical jump as viewed from the uniformly rotating frame. In this article, a few simple physics concepts are used to form a general solution to the initial question. (ERIC). |
