Gravitation and Mechanics
Gravitation, a fundamental law of the universe, is the mutual attraction of all masses in the universe. The equation used to calculate the gravity at the surface of a planet is F=mg, where Fis the gravitational force, m is the mass of the object, and g is the acceleration due to gravity. The principles stated in Principia, Sir Isaac Newton’s book that describes his laws of motion, are the three ways to change the momentum of a body: the law of inertia, the law of acceleration, and the law of action-reaction.
Johannes Kepler described three laws of...

- Earth is the third planet from the sun and the densest planet in our Milky Way Galaxie. Earth has a radius of 3,959 miles and the age of 4.54 billion years. The distance from the earth to the sun has shown to be approximately 92,960,000 miles. The Earth is divided into several layers which have a variety of chemical and seismic properties (depths in km): 0-40 Crust 40-400 Upper mantle 400-650 Transition region 650-2700 Lower mantle 2700-2890 D" layer 2890-5150 Outer core 5150-6378 Inner Core The crust varies in thickness throughout earth....

- Planet X. It sounds like something from a science fiction movie. There has been a lot of speculation about whether or not planet X really exists. Many people are obsessed with the theory that it exists and have done some really crazy things ,such as threaten suicide, because they are so disturbed about the planet. Maybe that is why it is also called the “doomsday planet”. Planet X has also been named Nibiru and is considered the twelfth planet. The name Nibiru came from a book written by Zecharia Sitchin....

- Solar nebula is a rotating flattened disk of gas and dust in which the outer part of the disk became planets while the center bulge part became the sun. Its inner part is hot, which is heated by a young sun and due to the impact of the gas falling on the disk during its collapse. However, the outer part is cold and far below the freezing point of water. In the solar nebula, the process of condensation occurs after enough cooling of solar nebula and results in the formation into a disk. Condensation is a process of cooling the gas and its molecules stick together to form liquid or solid particles.... [tags: disk, condensation, rotate, planet]

- The reflective shiny silver metal doors hissed open and Cede Nazzzuuh strode majestically into his quarters. The doors gave their snake-like hiss again and slid shut behind him. Cede went straight for the exquisite, luxurious couch set by the middle of the spacious ‘living room’ and threw himself onto it. He was exhausted. It had been a very busy but fruitless day. Today unlike the last five days they didn’t find anything of value to him from the alien ruins. It was seven days since they landed on the planet but they only managed to find four gold statues and two gold masks.... [tags: aliens, planet, news, space]

- A smile flickered across her face as she realized why she agreed to come along with him. She’d agreed because it was an excuse to fly her anti-gravity fighter craft. She didn’t give a damn about exploring dead worlds and wandering planets. She wasn’t the touring kind; there was nothing interesting in exploring dead worlds. Not for her anyway. There definitely wasn’t anything worth writing home about out here on the dead planet, only ruins left behind by an alien civilization long dead. “I heard you loud and clear the first time.” A suprisingly deep but friendly amused voice came through the high definition 3D sound communications system installed into the ship....

- My friend and I went to the AMNH on Saturday and we saw all the exhibits. We went to the Hall of Biodiversity first, and then Gottesman Hall of Planet Earth, the Heilbrunn Cosmic Pathway, Cullman Hall of the Universe, lastly is the Spitzer Hall of Human Origins. It took us three hours to visit all the exhibits. The first thing we saw was a giant clam and on the wall was the name Hall of Biodiversity. There were aquatic animals hanging on the ceiling from sharks to stingrays. I could barely see the aquatic animals because there was not a lot of lighting.... [tags: Earth, Universe, Planet, Human]

- Introduction Pluto will always be considered a planet to me despite what NASA and the IAU has to say about it. As a kid, I was always fascinated by Pluto; since it was the smallest of the 9 planets. The main reason was because it is the smallest of the planets in our solar system and was the last of the 9 planets to be discovered. In 2006, when I learned that Pluto was downgraded to a dwarf planet by the International Astronomical Union (IAU), I was disappointed because it no longer met the newly developed criteria for it to be categorized as a planet....

- Mars Introduction Mars is the fourth planet from the sun and also the seventh largest in the solar system. The month “March” was derived from its name. Mars has been known and observed since the ancient times. It is many times called the Red Planet. It is believed that people associated Mars’ red color with bloodshed and war; thus giving the reason behind its name. People have been studying this planet for centuries and have always been intrigued by Earth’s closest celestial neighbor. In 877, Mars’ moons Phobos and Deimos were discovered by Asaph Hall....

- Mars Mars is the fourth planet from the sun and the last of the solid, non-gas planets in our solar system. Mars is the seventh largest planet in our solar system. The diameter is about 4,220 miles. The equatorial circumference is about 13,259 miles. Earth’s equatorial circumference is about 24,901 miles so Mars’ equatorial circumference is approximately 53.2% that of Earth. The radius of Mars’ core is 1,056 miles. The surface area is 55,742,106 square miles, which is about 28% that of Earth. Mars’ volume is 163,115,609,799 cubic kilometers.... [tags: Fourth Planet, Sun, Solid, Non Gas, Solar System]

- Jove, Jowisz, the gas planet, the stormy planet, whatever you call it, these are all names for the biggest planet in our solar system, the fifth planet from the sun, Jupiter. The Romans named this planet after their god of the sky and thunder. This planet has 318 times as much mass as the earth, and its diameter is 11 times the earth’s diameter. Since this planet is the fastest spinning (rotates in less than 10 hours), it is flattened at the poles and it is bulged at its equator. One Jovian year (the time it takes to orbit the sun), take 11.9 earth years.... [tags: biggest planet, solar system, great red spot]
