Physics of Meteors :: physics space meteor falling star

A falling star is really a meteoroid and is a form of space debris. They be not really stars at all. There are cases where meteors have weared the humanitys atmosphere. In about cases, Meteors burn up upon entry into the atmosphere and never deliver it to the get up of the planet. There are times when the meteor starts to burn up, but because the muddle is big enough, it makes it to the surface, smaller accordingly when it started out. Through both means, the meteor deals with both(prenominal) measure of resistance upon entering the atmosphere. The main resistance that the meteor encounters is standard pressure resistance (or drag). Due to this collision with the atmosphere, the meteors surface begins to coalesce and vaporize causing the meteor to start breaking apart at its outer layers.When a meteor enters Earths atmosphere, they enter at a minimum velocity. This minimum velocity is about 11km per second (25,000 miles per hour). That is speedy then a bullet be ing fired from a gun. That is scarcely the minimum there are meteors that can get going such(prenominal) faster. Another comparison to this is that a space shuttle moves around the Earth roughly at about 8km per second.Most meteors burn up when they enter Earths atmosphere. There are a few meteors however, that make it to the surface. The ones that make it to the ground are called meteorites. Not all meteors are the alike(p) material wise. Some meteors are made out of rock, while others are made out of iron. Some even have a diversity of both, but in most cases, it is one or the other. A diversion fact that came up is that as much a 4 cardinal meteors fall to the Earth each day. Most of them are not real enough for anyone to notice. Another one is that the Earth gains about a million kilograms of mass a day from meteors.If you let N equal the add together of stone meteorites, which fall on one km2 of the surface of the Earth during a one-year per iod and N, includes all meteorites with a mass greater then or equal to m kg. The rate of the number of meteorites that touches down is
