  1. I love how you connected it to the movie! This is one of my old favorites!
  2. It so cool to think that once this type of movie was meant to seem fictional and now this can actually be seen as something that is true!
  3. When your in the shower belting out songs so know one can hear you i bet you have never thought that singing would have anything to do with physics. Well youre wrong! It totally does! People can not only hear your singing but they can also feel it! By singing, your voice creates vibrations that form into waves. Sound can be represented in wave form. The amplitude of the wave (the height of the wave) is represented by how loud you are singing. The amplitude is the degree of displacement of teh vibrator. Singing at a louder pitch create more vibrations, while singing at a soft pitch doesnt creat
  4. I really liked that you picked a unique topic like this and related it to yourself!

    Roller coasters!

    I never knew that a roller coaster uses its own energy to go up the second hill that's so interesting!
  6. Have you ever looked up into the sky and seen a type of air craft fly over your head. Have you ever wondered how that is possible? Many people would think that since an airplane or helicopter is so heavy there is no way that something like that could fly through the air. But through physics aircraft can fly thorugh the sky. there are four basic components of flight: thrust, drag, lift and weight. Also Newton's first, second, and third laws apply to flying. Newton's first law claims that everybody remains in a state of rest or uniform motion unless acted upon by an external unbalanced force
  7. Wow! I didnt realize that birds can fly up to 40 miles an hour, Thats fast! Great post i would have never thought to connect birds with physics!
  8. So cool! i will never have an energy drink again!
  9. Many people dont realize that there is more to boxing than just hitting someone and trying to knock them out. Physics applies to most of boxing! Energy, momentum, work, power, and velocity all play an important role in throwing a punch during boxing. Before the boxer punches his target he has potential energy which is stored energy,as soon as the boxer punches his target his or her potential energy becomes kinetic energy. Kinetic energy is the energy that a body possesses by virtue of being in motion. The higher the kinetic energy is the harder the punch will be. The equation for kinetic e

    Car Collisions

    I never knew there could be so much physics in car crashes! I liked how you connected it to newtons third law, great post!
  11. How does physics relate to rockets? How can people caluculate how rockets will fly given the parameters? Rockets fly mainly because of newton's third law and the conservation of momentum. Newtons's third law states that for every action, there is an equal and opposite reaction. To figure out how a rocket will accelerate you would need to learn about momentum. when a rocket is moving through space with a constant velocity, it is very simple to calculate its momentum. The equation for momentum is p=mv. This is momentum (p) equals mass(m) times velocity(v). This also includes direction; if a
  12. I wish i knew about the physics portion of playing basketball when i played, maybe it would have helped me be a better athelete at playing basketball! Great connection to physics!

    Infrared Waves

    SInce infrared waves can detect plant life on earth, does this mean that NASA could take pictures of other planets by using infrared waves and searching for other planents with life on it?
  14. i liked that you connected to physics with a sport! Usually people never think sports relate to science!
  15. Most people dont realize that there is science through playing a sport. Watching or playing volleyball is a great way to grasp the principles of physics. Understanding physics can be tricky if you just look at the mind boggling equations and such, but by connecting physics to other things, such as volleyball, physics can help you learn in an easier way. Gravity Gravitational force impacts every aspect of volleyball; whether you are serving, passing, or hitting. Gravity will effect every contact with the volleyball. When some one is going to serve, the server uses upward and forward force
