**Crossing A Carousel**

Figure 5 shows another example comparing the observations of an inertial observer with those of an observer on a rotating carousel. The carousel rotates at a constant angular velocity represented by the vector **Ω** with magnitude ω, pointing upward according to the right-hand rule. A rider on the carousel walks radially across it at constant speed, in what appears to the walker to be the straight line path inclined at 45° in Figure 5 . To the stationary observer, however, the walker travels a spiral path. The points identified on both paths in Figure 5 correspond to the same times spaced at equal time intervals. We ask how two observers, one on the carousel and one in an inertial frame, formulate what they see using Newton's laws.

### Famous quotes containing the words crossing a and/or crossing:

“Nature is a setting that fits equally well a comic or a mourning piece. In good health, the air is a cordial of incredible virtue. *Crossing a* bare common, in snow puddles, at twilight, under a clouded sky, without having in my thoughts any occurrence of special good fortune, I have enjoyed a perfect exhilaration. I am glad to the brink of fear.”

—Ralph Waldo Emerson (1803–1882)

“This was charming, no doubt: but they shortly found out

That the Captain they trusted so well

Had only one notion for *crossing* the ocean,

And that was to tingle his bell.”

—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
