Gravity plays a very major role in the formation, structure, and evolution of stars and their planetary systems. Planets are kept in their orbit around a star rather than falling into the star due to gravity and their velocity. In Earth’s case, the pull of the sun’s gravity and Earth’s velocity keeps it orbiting around the sun. The planets are traveling at a velocity that is perpendicular to the star they are orbiting. Therefore, if the star (sun) was not pulling them in using gravity, the planets would simply continue in a straight line. This is where Newton’s first law come into effect that states that an object will remain in uniform motion unless acted on by an external force. The star pulling the planets in is the external forces acting
The Earth revolves around the sun due to the gravitational force between them, so the Earth is pulled by the gravitation between it and the Sun. The Sun moves in an orbit as well due to the same gravitational force between it and the planet, which is the same as in real life. Also, the Moon revolves around the Earth like the moon revolves around the planet. It can be observed that the moon moves faster when the planet (Earth) is closer to the sun. This can be confirmed using Kepler’s Second Law (Equal Areas) because it states that the speed of the planet constantly changes and becomes faster when it is closer to the sun because it is in an elliptical
The Law of ellipses, which means that each planet travels around the sun in an ellipses.
| 17. Which of the following statements regarding the motion of objects on the celestial sphere is true? Answer
One important reason that the world that Laura and Howie encounter was more dangerous and malevolent rather than caring, supportive, and worth exploring is that Howie and Laura were excluded at camp from everyone else. According to Brock Cole “They took everything from me, I was stranded”. What Brock Cole is saying here is that Howie and Laura were left on an island, that is really dangerous to be left on an island alone, how would we know there safe? What would they do if they drowned then what? Now some might argue that, it was just a harmless camp joke, but the argument that Laura and Howie encounter was more dangerous and malevolent rather than caring, supportive, and worth exploring is still true.
8. Gravity is the force that is keeping the asteroid in orbit around the sun. The force of gravity will pull the asteroid inward, but because the asteroid is constantly moving forward- it is sort of a constant state of perfectly balanced tug-of-war.
If the planets were indeed orbiting the earth, they would have to move in very complex patterns. Copernicus said a simple circular orbit would account for the planets' movements if they were orbiting the sun. This became known as the Copernican Theory. Copernicus was one of the first to come up with a new idea to support his observations instead of making his research fit his
This demonstrates that, even though the weight of the stars is noticed, it doesn't impact
Exoplanets are interesting to us for a number of reasons. By locating and observing them, we are able to gather a variety of useful data that tells us details about the planet, and then compare and contrast them to other exoplanets, as well as our own planet Earth. These comparisons are our attempt at better understanding the formation history of rocky planets such as the one we live on today, and furthermore understand the future of rocky planets based on their internal composition and proximity to their host stars.
"Our solar system consists of one star and some debris," said Carl Sagan. There are many differences and similarities between the Inner and Outer planets. Our solar system is comprised of the Sun being in the middle, then followed by planets rotating it. The planets which orbit the Sun are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. The Inner planets are very different from Outer planets and the Outer planets are completely different from Inner planets, but both are very similar in many ways. Our planets in the solar system have many similarities and differences.
these planets have different names mostly consisted of numbers and letters. No indications of life
As our proto-sun was forming and spinning gases such as hydrogen and helium were pushed to outer rings of the nebula. Dust grains near the sun started to collide and overtime the particles and the collisions grew larger. Furthermore, gravity pulled these some of pieces together at a faster rate and over time this process created small planets or planetesimals . As these planetesimals grew larger they combined and created the planets closest to the sun : Mercury, Venus, Mars and Earth.
The United States is increasingly becoming a multiethnic, multicultural group of citizens. Life is no longer similar for all individuals. As people migrate they bring with them their cultural views, beliefs and language (Bhugra and Becker, 2005). In order to live together with respect, dignity and without prejudice for all, the country has had to educate itself on the beliefs and values of these vast cultures migrating to what they perceive as a land of opportunity whether this be for economic, education, or political reasons. For the most part in today’s world, cultural groups are intertwined in where they live, work, and attend school. To maintain a civil society, awareness
The reading on terrestrial planets from chapter 6 provides readers with a little insight on the similarities and differences between the planets. These planets include Earth, Venus, Mercury, and Mars. Although these planets have very different properties, they are connected due to their history. There are scientific laws that help people understand, compare, and contrast these planets, such as gravity, chemical composition, and temperature.
All Saints Day, which is celebrated in Guatemala, is a day of celebrating loved ones who have died. This day,“Dia de los Muertos, or the Day of the Dead, originated in Mexico centuries ago.”1 It is a day of joy and not of sorrow. This is the when people pray for help from the saints who have passed on. They also pray that those who have died without becoming saints will become saints. Fancy decorations, food, and fun are all joined together to help celebrate this day in Guatemala.
