Student Perspective

## Physics in a Strum

All you guitar players out their ever wonder why your instrument sounds SO different and unique compared to say a tuba? Well the simple answer is physics. I hope that by the end of this post, you will understand why. A guitar string is a common example of a string fixed at both ends which is elastic (meaning springy and flexible) and can vibrate. The vibrations of strings on the guitar are called standing waves, and they represent the relationship between wavelength and frequency. This simple

## Vroom Vroom! Nascar and Physics

Although I'm not a nascar driver I know that those cars go extremely fast...I mean it doesn't take a rocket scientist to figure that one out. The question is how do those cars maintain there outrageous velocity and still safely glide on the track? How is this even possible? One simple word: physics. Have you ever heard of friction? Well, if not, friction is the resistance that one surface or object encounters when moving over another. In physics language friction is represented in eq

## Pump up the Energy!

Do you ever just feel out of energy? But at the same time you want to work out? Ladies, it's time to motivate ourselves...summer is around the corner! So get off the couch, put the potato chips down and indulge in the physics behind working out and how "energy" is a misinterpretted excuse- trust me you have plenty of it! You see 5 hour energy drinks are actually falsely advertised. The company claims that you're body will never crash hours after drinking the solution....well they're wron

Unfortunately we can't dodge the physics regents exam BUT the good news is we can dodge dodgeballs in gym class. So yes, that was really corny intro sentence but, you'll thank me later the next time you go to participate in this scary sport :-) Remember the 5 D's: Just kidding, that's from one of my favorite movies: dodgeball. But physics believe it or not has everything to do with dodgeball- throwing, catching, running. When you throw the ball you are inacting a force, velocity, dist

## Dancing Through Physics

Have you ever wondered how and why dancing is so unique and special? Well believe it or not, a lot of it has to do with some basic physics concepts like velocity, force, and momentum. Some basic defenitions for your knowledge... Velocity; the rate in which an object is going in a certain direction. Force; lack of better terms a push or pull. Momentum; the mass of an object times its velocity. There are many forces that act on a dancer. For example, examine this picture. In this picture
