Part A
The Earth is orbited by 2,271 satellites, 10,000 rocks and debris and over 500,000 pieces of junk and smaller debris. But what forces are causing this to occur? Eccentricity is a measurement of how much the conic section deviates from being circular. This means that it is a measurement of how much the orbit (in this case) deviates from the 0 or the center.
When a satellite orbits the Earth in moves through an atmosphere depending on the satellite, when this occurs it can begin to venture inwards or outwards of the orbit due to Earth`s seasons and direction change creating a fluctuation in the amount eccentricity the …show more content…

In other words ellipses can be round or elongated; the degree of stretch is known as eccentricity. Eccentricity is defined as the ratioc/2a. C defined as the distance between the two focuses of the ellipse and a is the semi-major axis. In fact, a circle is an ellipse with an eccentricity of zero. Kepler`s second law is the speed of the planets along their elliptical orbits is such that they sweep out equal areas in equal periods of time. This means that the nearer the planets are to the Sun, the faster they travel along their orbit, so that a line drawn between the planet and the Sun can sweep out the same area. The third of Kepler`s law is the Square of the period of any planet is proportional to the cube of the semi major axis of its orbit. The equation for the law isT^2/(R_av^3 )=k. In the equation k is the constant. This rule is used to describe and calculate the relationship between the distance of planets from the sun and their orbital periods. According to this law the expression P2a−3 has the same value for all the planets in the solar system. In this expression P is the time taken for a planet to complete an entire orbit around the sun. A is the mean value of the maximum and minimum distances between the sun and the planets. The constant in the corresponding formula in Newtonian form is:
P^2/a^3 =(4π^2)/G(M+m) ≈(4π^2)/GM=Constant
In the following equation M is equal to the mass of the sun, m equals the mass of the planet. G is the gravitational constant. Because the sun us much heavier than any planet, Keplers third law correlates to Newtons equations (Laws Of Planetary Motion,

After Brache’s death, Kepler inherited his astronomical data. Johannes Kepler of Germany was inspired by the Neoplatonism and his continues sighting of Brahe, he set forth his solution for what is keeping the planets in their orbits. Kepler was able to affirm that the solar system itself is regular and it is organized by mathematically determined relationships. Both Tycho Brahe of Denmark and Johannes Kepler of Germany laid groundwork for Isaac Newton and his

This goes hand in hand with Newton's Laws of motion and universal gravitation. Newton's law of universal gravitation states that a particle attracts every other particle in the universe using a gravitational force and Newton's law of motion states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. Newton's Laws back up Kepler's laws by explaining how the planets orbit is an ellipse with the Sun at one of the two foci or center. The force that allows this to happen to the planets are explained by Newton's law and that the gravitational force is moving the planets into rotation, as by the law of motion. These forces assisting each other can make phenomenon's occur such as tides.

In the years of 1500-1700s, there were many new ideas in Europe after the Renaissance. With these ideas scientists started to discover, there were new medicine and new systems to find out ideas quicker. Although many people liked this new era of technology, this deeply troubled the church. The Scientific Revolution and the Enlightenment made the church furious because they believe everything was created by God. However, scientists like Newton, Kepler, Copernicus, and many more were able observe and conclude ideas, the microscope and other instruments improved observations, and others like Thomas Hobbes created a social contract so many people can speak freely, Scientific Revolution and Enlightenment considered to be a success in Europe and

However, Leavitt began to notice the relation between the brightness of a star and its’ period. A brighter star would exhibit a longer period for it to be at maximum brightness, dim down to minimum brightness, and brighten back to maximum brightness again. Leavitt graphed out the relation, showing that the brightness of a star and its’ period followed a straight line. This discovery is known as the “period-luminosity relationship.”

From that measurement and the ratio of the two orbit sizes, the size of Earth's orbit comes. The Earth's orbit is known with a precision of a few meters 2. Parallax Method The most important fundamental distance measurements come from trigonometric parallax. As the Earth orbits the Sun, the position of nearby stars will appear to shift slightly against the more distant background.

One of the reasons Pluto isn’t a planet is because of its size. If Pluto isn’t a planet then Jupiter shouldn’t be a planet. This proves that planets shouldn’t be based on a size. Based on my logic, Pluto orbits the sun. If it wasn’t a planet it wouldn’t orbit the sun because all the other planets orbit the sun and Pluto does.

By establishing that gravity, introduced by Galileo, played a role in the orbital understandings of Kepler, Newton also presented the law of universal gravitation in application to these three universal laws of motion in his 1687 publication. Newton’s development of his law of gravity corroborated Kepler’s theory of elliptical orbits and propelled a new method in the research of physics. Newton himself wrote the sentiment that, “To the same natural effects, we must, as far as possible, assign the same causes.” The findings of Newton prompted physics research to focus on patterns in the natural world that are universally

During the Middle Ages a Roman Astronomer named Ptolemy came up with the theory that all surrounding planets orbited around the Earth. Advancement in telescopes and technology helped Copernicus during the renaissance create a more logical and accurate theory which stated how the sun is in the middle of our universe and all planets orbited the sun. This changed the way man thought because it realized how small Earth is compared to the rest of the solar system and how we may not be

The vast majority think about cheerleading as a feeble action that requires young ladies sprucing up in charming garbs and waving around tufts. On the other hand, cheerleading is an exceptional game that requires practice, devotion, and learning of abilities. Much the same as some other game, material science is included in cheerleading 100%. Material science is found in each and every movement and trick. Cheerleading depends on tricks, tumbling, and bounced and since material science is so included in this game it makes this game really exist.

A Rube Goldberg machine is a complicated machine built to do a simple task. This type of machine was invented in the early 1940’s by Rube Goldberg. Rube Goldberg machines are made by combining various simple machines. The three simple machines that I will b using are inclined plane(s), lever(s), and when and axle(s). Inclined planes are very commonly used simple machines and consist simply of a flat, sloping surface.

Today virtually every child grows up learning that the Earth orbits the Sun, but four centuries ago the heliocentric solar system, where the Earth orbits the Sun, was so controversial that the Catholic Church classified it as a crime of heresy (UCLA). In the age of early philosophy, Socrates’ is well known. Between the Socratic method and his line of successful students, Socrates’ makes the history books. Galileo Galilei turned astronomers on their heads when he discovered moons around Jupiter. Giordano Bruno didn’t back down from any of his brilliant and different ideas.
