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…

galaxies work, and it shows that dark matter is real. It has its own separate existence apart from other components of galaxies”. The fact that a galaxy exists which prescribed to the Newtonian rules of physics without the presence of dark matter proves that it is not a flaw in the laws of physics that creates the gravitational problem. Essentially, the fact that a galaxy exist which definitely does not contain dark matter (or at least not measurable levels of it) proves the unusual…

Eugenia Cox gave birth to Elbert Frank Cox. Growing up as the oldest of three brothers, Cox took on his father’s love for education as he was the principal of a local elementary school. When Elbert attended High school he showed an unusual ability in physics as well as mathematics and was immediately appointed to Indiana University. During his studies at Indiana he joined the Kappa Alpha Phi fraternity and was elected to undergraduate offices. After Graduating in 1917, Cox Enrolled as a private…

inspired me to strive for a career in the aerospace industry. Researching into "How feasible are propulsion theories for interstellar travel?" for my EPQ allowed me to gain a deeper understanding of aerospace engineering. I was immersed in the physics and engineering world when I explored unfamiliar areas such as Antimatter Rockets and Special Relativity. Reading Brian Cox and Jeff Forshaw's "Why Does E=mc2?: (And Why Should We Care?)" made me realise that it was possible to achieve long…

The Physics of Cheerleading The sport I chose to do my essay on was cheerleading, because of the physics shown all throughout the sport. There are stunts, tumbling, and jumps. Cheerleading is a sport that involves all these tasks and much more. Cheerleading consists of many concepts of physics, such as Gravity, Newton Laws of Motion, momentum, torque, potential and kinetic energy, velocity, force, gravitational acceleration, free fall. I will explain the definitions of each concept, so readers…

Otto Hahn was born in Frankfurt, Germany, in 1879. Hahn quickly took an interest in chemistry in his early years. By 1897 at age 18, Hahn was attending the University of Marburg studying chemistry. After taking his doctorate exam at only age 22 in 1901 and then working as an assistant at the University of Marburg, Hahn moved on from organic chemistry into the field of studying radiochemistry and radioactivity in London with Sir William Ramsay, the British chemist most known for discovering the…

“It would be better for the true physics if there were no mathematicians on earth.” Daniel Bernoulli once said this statement. Not many people know about Daniel Bernoulli. Daniel Bernoulli (He was also known as Daniel Bernovllivs), was a swiss mathematician that furthered the study of calculus and physics along with his family. He was known for his principle (Bernoulli’s Principle), but also did many other things with his time. He helped the field of hydrodynamics, and without knowing it helped…

This allows me to solve problems in many other areas such as Physics. I have attended a university lecture on solar panels at the University of Leeds; this showed me the diversity of mathematics and demonstrated how a seemingly abstract concept has such practical applications in solving modern day problems. The area…

What is refraction Refraction is the bending of light when it passes from one medium to another, as light travels through one medium such as air it will travel at a certain velocity but once it enters another medium such as glass it will change direction due to the increase in density of the medium which slows down the velocity of the light. The amount that the light bends as it travels through a medium depends on how drastic the difference in optical density is. For example if light were to…

Snowboarding is a very dangerous sport to be in. Going at a fast speed and dodging trees and also on a steep trail could be life endangering. That is why it is important to be experienced and to have all of the stated safety equipment on. As you can see in the image to your left you can see all of the safety equipment that you will be used to keep you safe. At the bottom you can see all of the equipment and how it will help guard your body into fuller detail. HELMETS The brain is a very…
