  1. Wind is the flow of gases on a very large scale. Wind is caused by the differences of pressure in the earth’s atmosphere. Wind is caused by two major factors on the planet earth. The first being the sun and the second being the rotation of the planet. The sun does not heat up the earth’s atmosphere evenly, as most of the solar energy is absorbed at the equator. When the air becomes heated it expands creating an area of higher pressure. Diffusion causes this area of higher pressure to move to an area of lower pressure. On a very large scale this would massive amounts of air to travel from one a

    physics of a bed

    Very interesting!
  3. We know that moving objects have momentum. Unless an outside force acts on an object, the object will continue to move at its present speed and direction. Cars consist of several objects, including the vehicle itself, loose objects in the car and, of course, passengers. If these objects are not restrained, they will continue moving at whatever speed the car is traveling at, even if the car is stopped by a collision. Stopping an object's momentum requires force acting over a period of time. When a car crashes, the force required to stop an object is very great because the car's momentum has cha
  4. A great place to begin to understand the physics of nuclear weapons is with Einstein's most famous equation: E = m*c*c. This equation associates energy E with mass m. The constant of proportionality is the square of the speed of light c. Because c is rather large (3E8m/s), the equation suggests there is a lot of energy associated with even a small amount of matter. In fact one kilogram of matter contains 9E16 Joules of energy, which is roughly the amount of energy released by a hydrogen bomb. Chemical reactions, such as the combustion of petrol in car engines, free less than a billionth of the
  5. this is awesome! physics really is all around us
  6. The Composition of stars is a very important and interesting field for astronomers. Stars begin their life when an ordinary dense cloud of interstellar matter becomes unstable and begins to collapse. The composition of such a cloud of matter determines the composition of the star which results from the collapse. Astronomers study the spectrum of the Sun to determine it's chemical composition, since it is the biggest star we are familiar with. In the visible region alone, from 4000 to 7000 angstroms (10-10 Meters), there are thousands of absorption lines in the solar spectrum. These lines have
  7. i love shopping! physics really can relate to everything.
  8. I have a very large interest in bees, so for my first blog post I've decided to research how bees see colors differently compared to humans. Through my research I have discovered that the color spectrum of bees is shifted when compared to the color spectrum of humans. Visible light is part of a larger spectrum of energy. Bees can see ultraviolet – a color humans can only imagine – at the short-wavelength end of the spectrum. So it’s true that bees can see ‘colors’ we can’t. Many flowers have ultraviolet patterns on their petals, so bees can see these patterns. They use them as visual guides
  9. Our balls velocity had a 30.5% percent error, which makes our resuslts very unreliable. There could have been many reasons why our percent error was so high, disregarding human error. With such a short distance of 2m, the stop watch could have been started or stopped to early or too late, this messes up our times. No one has super sharp reflexes so timing really negatively affected our experiment. The position of the ball as it was dropped was also an issue because there was no way of knowing that each time the ball was dropped it was in the same position as in the other trials. if we could re
  10. Young physicists at Irondequoit High School have calcuated the acceleration due to gravity. They used kinematic equations to determine the acceleration due to gravitty using a tape measure, a ball and a stop watch. During the first method, the students measured how long the jumper was in the air with a stop watch. The students took three trials and found the average in seconds. Then, they used their kinematic equations to find the displacement. With these two particular students, using the stop watch their displacement calculated out to be .36cm and .22cm. During the next method, the students
