Circus Physics: Centripetal Acceleration
Video duration: 2:12
Trick riders may just ride in circles, but that doesn't mean they aren't accelerating. Moving in a circle requires steady changes in direction. This is a form of acceleration directed inward, the same acceleration that we feel when going around bends in a car, and that holds us in our seat on the rollercoaster. In this video, you'll learn the basics of circular motion.
