AP Physics 1: Forces 24: Circular Motion 6: Ferris Wheel

• • I was trying to find a good Ferris wheel to use for this problem. I looked at those giant Ferris wheels and found that they are usually for sightseeing and therefore move slowly and have small acceleration. Remember we feel acceleration? Lower acceleration provides better comfort : ) So for the problem used in this video lesson, I chose the Ferris wheel in Youtube video: http://www.youtube.com/watch?NR=1&v=1GG7ajmWtKY&feature=fvwrel . I estimated the radius and measured its rate of rotation to get the r = 9m and the 6 rev/min for the problem
