In the absence of forces, motion in a straight line and constant velocity continues indefinitely. Motion in a circle, however, requires forces to act. ... Since its velocity v equals the distance it moves in one second, one finds . ... The above result suggests that steady motion around a circle, at least for a short time span, can be viewed as the sum of a straight-line motion with fixed velocity v , plus an accelerated motion towards the center of attraction, with the above acceleration, a . ...

. Next: Spectral types Up: Optional stellar data Previous: Optional stellar data . Proper-motion information requires three columns: the separate components, and the epoch of the catalog position. We follow the SAO Catalog in using annual proper-motion units of seconds of time per year in R.A., and seconds of arc per year in Dec. The epoch is given in decimal years. The respective column labels are MUALPHA, MUDELTA, and EPOCH. These are all Real*4 data. Pascal Ballester . Tue Mar 28 16:52:29 MET DST 1995
