Gravitation

Introduction Gravity is a natural force that is the result of various distributions of matter and energy throughout the universe. All objects have gravitational pulls but as an object becomes more massive, its gravitational pull increases and takes precedence over the gravitational pulls of other smaller objects as demonstrated by the solar system in which Earth resides. Earth’s moon rotates around Earth due to Earth’s gravitational pull while Earth rotates around the sun due to the sun’s…

Liam Naughton ESS 102 Research Paper Synopsis Jebadiah Kerbal is the first person given a mission to go to and return from Mars. However, due to complications and mishaps he will find himself stranded on a foreign planet with no hopes of coming home. His trip to Mars starts off relatively smooth but, during the landing sequence one of the fuel tanks bursts open. Now, with his spacecraft’s main engine dead, and no hope of returning to home Jeb decides to do what every great scientist would in…

Physics can often explain many of the everyday activities of life; from playing football to ice skating to visiting an amusement park. Most people step into an amusement park excited for the thrill of riding all of the roller coasters without ever giving any thought to the physics behind the ride. There are several components of physics which contribute to the thrill of roller coasters, including gravitational forces, the law of conservation of energy, friction, centripetal force, and normal…

The four fundamental forces have been around before mankind. These forces shape the way we live and interact with the objects around us on a daily basis. These forces are so important, they are in existence throughout the entire universe. Black holes, the formation of planets, galaxies and stars are all because of gravity and these same celestial bodies have their own electromagnetic forces and the strong and weak nuclear forces are. Since everything in the universe is made of atoms, there is…

Gravitation - Movement, or a tendency to move, towards a centre of gravity, as in the falling of bodies to the earth. (Oxford Dictionary) Introduction : For centuries, mankind has always been fascinated by the celestial bodies. The motion of the stars and planets were at once a symbol of the divine order of the universe and a profound challenge for human understanding. For the ancient Greeks the separation between the terrestrial and celestial realms was absolute--the downward motion of…

becomes absolutely black and human cannot observe it directly (Montgomery, C., Orchiston, W., & Whittingham, 90). In 1915, Einstein Albert, a great physicist, published the Einstein field equations which describes the fundamental interaction of gravitation as a result of spacetime being curved by matter and energy (Einstein Albert, 884). One month later, Karl Schwarzschild, a German physicist, got the accurate solution of Einstein field equations and deduced that if the mass of an object is…

which is a big brand of mathematics, this is still largely used in the world today. Also his most famous contributions were his theories of universal gravitation his his three laws of motion. The theories are widely accepted and his laws of motion are some of the most important aspects of science in modern education. His theory of universal gravitation also helped explain heliocentrism which explains how the Earth and other objects orbit the sun. Many of these things went against religious…

Fundamentals of Orbital Mechanics This chapter applies the principles of physics for describing motion of artificial satellites and planets which are moving under the influence of gravitation force. It also presents an accurate gravity model for flight dynamic applications (for use in subsequent chapters). 2.1 Kepler’s Laws of Planetary Motion In 1609 Kepler has presented his three laws for describing motion of planets around the Sun. These laws are empirical because Kepler has found them…

Albert Einstein was one the most important scientists of his time. Mostly because of his discoveries and theories.Two of his theories have caught my attention: the theory of relativity or the theory of gravitation. I have found his works to be entertaining and educational while also being realistic and inspirational. Albert Einstein was a brilliant mind in his time. Well into the 21st century, he still continues to teach and give insight on important matters such as studies on gravity and…

The human species is one that craves knowledge. An innate trait in human cognition has always led us to search for the understanding of why things happen. When thinkers across time such as Aristotle, Copernicus, Newton, and Einstein went searching for understanding of the cosmos, they realized that the question of “how” the universe behaves as it does is just as important as “why it does.” One example of this is the broad concept of gravity. The original question was “why do things fall?” This…
