    How Airplanes Fly

    So interesting!!! I always knew you loved volleyball! :-)
  2. When one plays a guitar, it is so important to remember all the physics behind it. Waves have a lot to do with the sound we hear from them. For example, without a large amplitude, it would not be heard. And when one changes notes, it changes the frequency that is heard. Because the wave is longitudinal, it needs a medium to travel through which is why in a vacuum you would not be able to hear someome playing. The pulses vibrate parallel to the wave because in a longitudinal wave thats their path. Also, playing the guitar has a lot to do with mechanical energy as one strums the strings. With

    Physics of Working Out

    Working out is a vital part of a healthty lifestyle and I always wondered how much physics is involved in it. Working out takes a lot of work because work equals force times distance. The amount of work I put in is based on my force and distance. For example, when I lift weights, the heavier the weight and the higher distance I lift, the more work I put in. Also, an important part of working out it doing cardio. I like to run fast so I need my velocity to increase. Average velocity equals distance divided by time, so when I am on the treadmill I try to run two miles as fast as I can so I ha

    Physics of Tubing

    Now that the nice weather is here I thought it would be appropraite to talk about my favorite summer activity, tubing on the lake! The best part of tubing is when your holding on for dear life and are going so fast the water splashes everywhere and then you take a big jump off a huge wave! But beyond just having fun there is a lot of physics involved. First, momentum is a huge part of tubing. Momentum is the product of an objects mass (me) times its velocity. This explains why I have so much more momentum than my little cousin does. Also, work is involved in tubing because my boat has to pl
  6. That's a great way to find the average velocity!!

    Car Collisions

    When a car accident occurs, how can scientists see the change in momentum? After two cars collide and become connected, how is it possible to find the mass, momentum or velocity of either car? Simple, the conservation of momentum. If the vectors of before the crash and after are added up, they will equal each other. This can be written in an equation as: P-initial=P-final This is directly related to Newton 3rd Law, which justifies that all gorces come in pairs. But this is not the only physics involved in car crashes. When poth cars are moving towards eachother, they are exterting kineti

    Physics of Modeling

    I've always wondered why models are so skinny. Beyond fitting the designers clothes, there really seemed to be no point in forcing them to be so thin. This thought made me wonder, is there any other benefit to being so thin, do they move faster down the runway and do they have more momentum? Then I realized, this is a physics problem! So how could I test if skinny models move down the same length runway faster and if they have more momentum, which is what lead me to two basic physics equations 1. V=d/t 2. p=mv To deal with equation one, and knowing I must solve for V, I would need to ti
  10. Hello I enjoy a lot of things outside of school. For example, I play a large part in the yearbook club and have taken classes at such places like FIT. I really enjoy fashion and learning all about the business end of it as well. I like to learn about things that intrigue me and am looking forward to learning more in this class! I am taking physics because I know it is beneficial for when i start applying to colleges. I think it will be a challenge and that by working hard I will increase my work ethic. This year I hope to learn about forces and why certain things happen the way to do. Over
