1. The relationship between Mercury’s rotational period and orbital period is a resonance. This results from the Sun’s tidal force on Mercury and its very elliptical orbit. The sun cannot lock Mercury into a 1:1 rotation due to Mercury’s high eccentricity. Mercury takes 59 Earth days to rotate and and 88 days to orbit so it spins three times for every two orbital periods.
For instance, the DVD with a radius of 4 has a circumference of 25.13 cm and a tangential speed of 1933.08 cm per second. During the activity, I noticed as the radius increased, the tangential speed also increased. I also noticed the shape of the rigid body rotation curve was linear. Therefore, the linear shape of the rigid body rotation curve demonstrated that the curve was a solid body rotation. In the second activity, I completed the table by determining the speed of the planets in the solar system.
Jedi The Juno Mission is a huge mission to see what the origin and evolution of Jupiter is and to trace our solar system 's history. Nasa’s scientist hope to see why Jupiter has the most radiation (Earth has 0.39 of cosmic radiation and Jupiter is expected to have 20,000,000 of a Rad over the course of the Juno mission). Juno will be the first ever mission that gets within 3,000 miles of Jupiter 's cloud tops. The Mission is going to be just the beginning of a huge scientific exploration of Jupiter and our solar system. Juno will see why Jupiter’s magnetic field is so strong.
Galileo Galilei also was in Astronomy and was known for Projectile Motion, Galileo was a confirmed Copernican and given to the concept of circular motion. Galileo 's 'facts ' differed from the traditional data of astronomy in that they were derived from qualitative telescopic observations. Some of the observation data that he collected from the telescope was that the phases of Venus were inexplicable in terms of Ptolemaic cosmology; Ptolemaic scheme no longer viable and the satellites of Jupiter, moving with, and approximately in the same plane as the planet, suggested more than one center of rotation in the solar system and, by analogy, the earth 's rotation around the sun. In his later theory (1632), no force is necessary to keep a body moving on a level (frictionless) plane; a body, as such, has no inclination to move or remain at rest, it is indifferent. Thus, if a body is indifferent to motion, no mover is required to sustain movement once a
Uranus, the sideways planet with 21 year long seasons. Discovered 235 years ago by William Herschel, Uranus is the 7th planet from the sun. The first planet, in fact, to be discovered with the aid of a telescope. Although this “planet” was spotted and charted in 1781 it wasn’t classified or universally accepted as one for a whole two years because it was originally believed to be a comet or a star. After it was finally accepted and titled, a planet, more research went toward Uranus.
Considered the father of modern science, Galileo made major contributions to the fields of physics, astronomy, cosmology, mathematics and philosophy. Curious with the world and stars around him, he designed an improved telescope which allowed him to view the moons surface, and as far as the rings of Saturn. In the 16th and 17th century, that is quite a feat. Also, Galileo had great contributions to the beginning phases of laws of motion. Having done many experiments of the rate in which objects fell, helping him develop the concept of inertia.
The telescope is named after Edwin Hubble, who discovered that there are more galaxies in the universe other than the Milky Way. He also discovered that galaxies are moving away from us and that the farther away they are, the faster they are moving. Edwin Powell Hubble was born in Missouri in 1889. He moved to Chicago 9 years later. He graduated from high school in 1906 with a scholarship to the University of Chicago and graduated from the University with a degree in Mathematics and Astronomy in 1910.
The people of medieval Europe also believed each sphere has its own solar system with stars, planets, and sun, and they all orbit around Earth. It wasn’t until Copernicus in the sixteenth century that the idea of the earth revolving around the sun was considered and it wasn’t until the eighteenth century that people started to think that the universe was “infinite in time and space.”( pg.2) According to Christian the modern temporal scales are as intimidating
In the pre-Copernican era, geocentrism was the paradigm for astronomers and philosophers. There were some thinkers, such as Aristarchus and Oresme, prior to Copernicus who advocated for heliocentrism or other models. However, the majority of philosophers and scientists held on to the physics and models of Plato, Aristotle, and Ptolemy. Nicholas Copernicus caused the paradigm shift from the idea that the Earth is stationary and central, to the idea that the Earth rotates and revolves around the sun. In De Revolutionibus Orbium Caelestium, Copernicus explains his stance on the shapes, movements, sizes, and positions of celestial objects (Danielson 104).
John Herschel discovered Uranus in 1781 while searching for double stars. There had been recent developments in Newton’s mathematics that would allow astronomers to calculate the orbits of celestial bodies and he wanted to learn more about the physical nature of stars. When he first saw Uranus through his seven-foot reflecting telescope, he thought it was a comet. Very few astronomers believed there was a possibility of more planets, other than the five they knew of, the moon, and the sun. It wasn’t until a Russian astronomer calculated the orbit of the “comet”, following a slow moving path, that it was determined that it was a planet.
Starburst galaxies can sometimes be the brightest things in the universe. This happens when they release ultraviolet rays, which are absorbed by the dust and then re released at infrared wavelengths. The formation of stars can be stopped if the remaining gas in the galaxy is blown away by stellar winds or a Supernova explosion. Starburst galaxies are less common now than they were in the early stages of the universe. These galaxies are about 12 billion
