I work at seabreeze over the summer. Amusement parks are literally playgrounds of physics. Rollercoasters rely solely on momentum to keep going, gravity keeps all the carts on the track, and so forth. The ride I want to focus on is the music express.
The music express has a plethora of physics. The most obvious is centripetal force. The music express travels in a circle at high speeds. This causes our bodies to fall towards the outside of the cart. In order to stay in, there must be some sort of acceleration towards the middle of the ride. This is known as centripetal acceleration. Without this and gravity working together, we would simply fall off the ride. OUCH!
Come to seabreeze this summer, and learn all about physics with your favorite trash grabber, yours truly.
