Introductory physics

Discussion – Tayla Dorrington Introduction There are 2 major theories about the universe and how it began. These are the steady state and The Big Bang theory. Both theories have an explanation on how our Universe is, how it began and how it works. Both theories have stuff in common but also have many differences that could completely change the way we look at the Universe. The Big Bang Theory has much more evidence supporting it, while the Steady State Theory has been proven wrong. Big Bang…

In conclusion, we can use Newton’s 3 laws of motion to maximize our rockets’ flight time. For Newton’s first law, our hypothesis stated the following: “We can apply Newton’s first law by minimizing the forces that resist motion. The way we will do this is to make the nose cone as smooth and pointy as possible. If the nose cone is too flat on the end, it will not cut through the air very well. The rocket must cut through the air swiftly, this means that resistance will be at its minimum during…

Jean Jacques Rousseau was a Swiss born philosopher. His father was an educated watchmaker. His mother died at childbirth and his father was exiled from Geneva. He had a hard time living with his mother's family. At the age of 16, he fled Geneva and went to France. Paris was culturally very different from Geneva. He suffered from deep isolation and his life was very unstable. He was involved in many strange affairs with women. However, he met a woman named Mme de Warens who was 10 years older…

fees. In 1666, the university was temporarily closed due to an extremely contagious, mortal disease and Newton was forced to return home. It was surprisingly during this time, when he was away from school, that he started to pursue his own ideas on physics. When the university reopened, Newton returned and took a fellowship in order to acquire his masters degree. Today, Newton is referred to as one of the most influential scientists that have ever lived. The emphasis of this essay will be on his…

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…

Proving Newton’s Second Law of Motion Aim: Prove that a (acceleration) is proportional to the net force and inversely proportional to the mass. Background Theory: Sir Isaac Newton presented his three laws of motion in the Principia Mathematica Philosophiae Naturalis in 1687. The second law, ΣF = ma, states that changes in force will cause an object to accelearate and with this equation, one can figure out how much. It can be rewritten into a = ΣF / m, and thus, it can be seen that acceleration…

It seems widely acknowledged that scientific knowledge is special because it is derived from the facts of experience with application of rigorous scientific methods such as observation, experiment, measurement, statistics, and theorization, to natural phenomenon. Other academic fields like literature and jurisprudence, for example, appear to be merely based on vague and inaccurate methods such as expressing personal experience or opinion, or applying rules written in words arbitrarily…

As we know most of the things we humans learn are by mainly active experimentation or passive observation. Imagination is also one way of learning. For example in physics the first structure of atom was first imagine by a scientist but then that keep on changing . What is active experimentation ? it is when you yourself do some thing new ,which is new to you. that is basically active experimentation. what is passive observation ? passive observation is when you see or observe something happening…

Rutherford’s planetary model. After his publication of his model he received worldwide fame. Unfortunately, Bohr’s model worked only for hydrogen atoms. Which made the final atomic model yet to be developed. In 1922 he received the Nobel Prize for physics in 1922 for his investigations of the structure of atoms and of the radiation emitting from them. Later on he served as a professor at the University of Copenhagen as well as the director of the…

The beam of electrons must hit the screen in one specific spot, as if you were throwing baseballs through a hole against a wall. (Hence quantum physics challenged our classical thinking about objects and was deemed controversial in its early years.) In fact, when a slit is closed, the interference pattern disappears — the photons or electrons form a single band that spreads out from the brightest…
