Meteors, meteorites, and Meteoroids

Authors note: This is my project on Meteors and there siblings. I am working on making my writing more specific and well described. I hope you enjoy it.

You could be sitting in your backyard looking up to the sky. You see the all of the stars shining brightly. Then out of the corner of your eye, you see something moving. You look more closely and notice that it is a Meteor. You are amazed at the hundreds of moving stars all around. Before you know it they all stop. You look around confused, wondering why they stopped. That is the beauty of a meteor shower.

There are three different types, or stages, of a meteor, all of which are very important. The first stage is a Meteoroid. This is a meteor that is currently in space or just eroded off of a comet or asteroid. These are very hard to see even with a telescope. There are millions of meteoroids flying around the universe waiting to be caught in a planets gravitational pull and be lead toward the next stage of it's life.

As a meteoroid falls through a planets atmosphere it becomes, it transitions in to the next stage, a meteor. During the fall to the ground, a meteor will become very hot and it will begin to burn up. When large amounts of meteors fall into the atmosphere, a meteor shower starts. During a meteor shower, meteors become very bright due to the large amount of heat. If a meteor can survive the heat and gets to the ground it become its last stage.

After a meteor hits the ground it becomes the final stage, a meteorite. When a meteorite hits the ground it is usually very small, this is because the heat it sustained still damaged the meteorite and burned layers of the meteorite off. You have more of a chance at winning the lottery than you do finding a meteorite in your yard and if you do find a meteor, it might be close to the size of a golf ball and could still way around 20 pounds!  
   

Seeing a meteor shower gives you the opportunity of seeing the most important stage of a meteor, it is the most common stage to see., the other two stages are a little harder. The life cycle of a meteor is a short one and is finished after it hits the ground. A meteor shower is an amazing opportunity to see something from space, something that many people will never be able to see, and that is the beauty of a meteor shower.

Physics

Authors note: In this project I started off working on a bunch of different types of sciences, but Mr. Johnson helped me narrow down my research so I get a lot more in-depth research. My goal for this piece was to be a lot more in-depth.

When most people think of science they think of old people In white lab coats, mixing random chemicals together, but science is much more.  Physics is a very important form of science, without it we wouldn't understand gravity or how a lot of other things work.

The first known model of Planetary motion was given by Kepler in the early 17th century which Proposed that the planets follow elliptical orbits, with the sun at one focus of the ellipse.

Galileo also made use of experiments to validate physical theories, a key element of the scientific method. In 1687, Isaac Newton Published the Principia Mathematica detailing two comprehensive and successful physical theories, Newton's Laws of Motion, Which led to classical Mechanics; and Newton's laws of Gravitation, which describes the fundamental force of gravity.

The beginning of the 20th century brought the start of a revolution in physics. The long-held theories of Newton were shown not to be correct in all circumstances. Beginning in 1900, Max Planck, Albert Einstein, Niels Bohr and others developed quantum theories to explain various anomalous experimental results, by introducing discrete energy levels. Not only did quantum mechanics show that the laws of motion did not hold on small scales, but even more disturbingly, the theory of general relativity, proposed by Einstein in 1915, showed that the fixed background of space time, on which both Newtonian mechanics and special relativity depended, could not exist.

 In 1925, Werner Heisenberg and Erwin Schrödinger formulated quantum mechanics, which explained the preceding quantum theories. The observation by Edwin Hubble in 1929 that the speed at which galaxies recede positively correlates with their distance, led to the understanding that the universe is expanding, and the formulation of the Big Bang theory by Georges Lemaître.

Without Physics, Life would be a lot more simple. We wouldn't know half of the laws of science that we know today. Other than Physics there are many other types of science that can help us understand a lot more. Physics is not alone.
