  1. As summer is so close to us, many of us go to amusement parks. Seabreeze is right around the corner from us and as you know, the Jack Rabbit is one of the oldest roller coasters! As i day dream about being on the coaster instead of studying for physics, i cant help but think of the physics that have to do with a roller coaster. There is much to think about when one thinks of a roller coaster! The mass of the cart and the people inside of it play a major role in understanding the concept of force. Force= mass X acceleration and the mass a person usually tries to find consists of the people
  2. ... maybe thats why i dread working out- too much work!!

    Physics of Working Out

    Next time i work out i'll definitely be thinking of you!!
  5. In the summer, my favorite place to be is the beach. Physics can be found everywhere, especially in the water. No matter where a person goes, you can almost always find physics around you. Every wave has a medium and in this case, the medium is the water. A medium is a substance or material that carries the wave. As a disturbance moves through a medium from one particle to its adjacent particle, energy is being transported from one end of the medium to the other. In every wave there is an amplitude and depending on how big the amplitude is, decides how big the wave is. The higher the ampli
  6. Today as i was driving i had to stop because a cop car was coming my way and needed to pass me. As a driver, it is just a procedure to pull over to the side of the road and wait for the cop to pass, then proceed on my way to wherever i was going without thinking twice about the cop car that had just passed. However, today i was listening extra carefully and thought to myself, "Why does the sound increase as it is coming towards me, but as soon as it passes, it decreases?" Thinking back to previous physics units this year, i remembered the Doppler Effect. The doppler effect is the shift in f
  7. Its weird that we used a mirror everyday before not knowing how it really worked!
  8. wow!! you're gonna be the next Derek Jeter, Brendo
  9. when roller blading, i would have never thought about this! Great Job!!
  10. I have played soccer my entire life and not once have i ever thought, "I wonder what the physics is when i kick the ball." To be honest, I dont think I have ever asked that... ever. To look back on it now, the entire game is made up of physics and without it, the game would not even be possible. Through Newtons laws of motion, the game of soccer can become an intense, physical, and well thought out game. Newtons 1st law of inertia states, any object at rest, will tend to stay at rest, and any object in motion, will tend to stay in motion unless acted on by an unbalanced force. The soccer b
  11. What would we do without gravity! I dont even want to know!
  12. I wish I could see like a bee! Good job!
  13. Ever since I was young I hated to sleep with my door open because i wanted there to be complete darkness. After the class lesson on diffraction, i now know that i am not actually sleeping in the complete dark. Diffraction is described as the bending of waves around small objects and the speading out of waves through small openings. Because of diffraction, I can infer that I am not sleeping in the dark, but the light. In my house, there is a hallway right outside my bedroom and my parents normally forget to turn off the hallway light before they fall asleep. However, when i go to bed, i just
