    Physics in Miss Congeniality

    One of my favorite movies is Miss Congeniality! If you have not seen it, number one, you should, but it is about an FBI agent who goes undercover in the Miss United States Pageant. Because she is not by any means a pageant star, for the talent portion she shows off her amazing skills playing music on different types of wine glasses. The reason sound is produced as she swirls her fingertip around the glasses is due to the principal called resonance. Resonance occurs when a system vibrates another system with natural frequency. Different size and shaped glasses cause differences in pitch because the sound wave vibrate differently due to their differing frequency. Nothing better than coming across some physics in one of your favorite films.

    Physics of Singing

    Since most of my life is spent in my voice studio, in room practicing or performing I figured it was time to write about some of the physics that go into singing. Recently, we learned that sound waves must travel through a medium. The medium in singing is air, so technically, sound could simply be described as moving air molecules or vibrating air molecules. One of the hardest things to master as a singer is perfect pitch and what pitch really is frequency of a sound wave or moving air particles. Therefore, when I sing in a lower register, my frequency is lower and in higher registers it is at a higher frequency. Being able to change back and forth between frequency makes for very successful singers as they can sing in both a high and low range. Singers spend years learning how to make a larger sound and a larger sound is created by larger amplitudes of sound waves. The higher the amplitude of the sound wave, the louder we perceive the sound being and the lower the amplitude of the sound wave, the softer we perceive the sound being.

    Physics of parisailling

    Ironically when I was a kid I hated heights but now I love rides and heights. So over February break my friend and I took a trip to Orlando and we spent some time at Disney. At the Contemporary Resort they have a water sports center and we went parasailing which was awesome. We got to see the whole Disney property from above. What was cool about parasailing besides the views was all the physics involved. Fro example, our parachute was hooked on to a boat and the captain had to ask us how quickly we wanted to travel, which determined our velocity and how far above the water we wanted to go, which determined our distance. It was really windy up there and that is when I realized why we needed a parachute, it was to help us with air resistance so that we did not go too fast and get hurt. Also, while we were up above I saw a ton of waves and the boat also created waves and as we speed up or rather the boat the waves became more frequency and got larger which fits with the wave equation.

    Physics of Universal

    Over February Break my best friend and I went to Universal Studios in Orlando, Florida! We went on a ton of rides and it was amazing how many rides involved precise physics. For example, one of their biggest attractions is Dr. Doom's Free Fall. The ride takes you up a lot like the spring at seabreeze and then drops you. The ride is 200 the air and you can see it while driving through Orlando. It advertises that the ride is faster than the space shuttle. It was interesting that they call it free fall because that is technically incorrect because it does not accelerate at 9.81m/s squared according to their facts and figures it is only as fast as a boeing 747 launch which is slower than free fall. Another ride that was cool was the Storm Force Accelatron which moves you in a close dorm. You experience what increasing and increasing a centripetal force which was interesting.
  10. Last week I babysat for 3 little kids. Their Dad build them a sledding hill out a slide. I took them outside after bundling them up and we went sledding. When sledding I noticed how easily the sled glided down the snow bank, then I thought, snow and ice have a low coefficient of friction. Additionally, I noticed that when the kids went down individually, they went quicker down the hill. Because Force equals mass times acceleration, acceleration is also equal to force divided by mass. Therefore, the kids went faster when they were by themselves because the mass was less and the acceleration could grow. Lastly, The kids dad also put a ramp at the end of the hill which slowed down the sled and changed its velocity. The change in velocity was helpful because without stopping the sled could of gone in the large tree in the backyard, because an object in motion tends to stay in motion unless acted upon by an outside force.
