advancement than the jet airplane. Since the early 19th century‚ beginning with Otto Lilienthal‚ to the Wright Brothers’ first airplane‚ humans have continuously strived to understand and improve upon the concepts of flight. Today‚ we have mastered the concepts of flight‚ as exemplified by the jet airplane‚ which is now the standard for modern air travel. To truly appreciate just how far we’ve come‚ it is important for one to understand how a modern jet airplane works. All airplanes rely on three separate

PHYSICS PROJECT TO STUDY THE OPTICAL LENS OF A HUMAN EYE Eyes are organs that detect light‚ and convert it to electro-chemical impulses in neurons. The simplest photoreceptors in conscious vision connect light to movement. In higher organisms the eye is a complex optical system which collects light from the surrounding environment; regulates its intensity through a diaphragm; focuses it through an adjustable assembly of lenses to form an image; converts this image into a set of electrical signals;

play and watch soccer games all of the time and yet few people actually realize the physics that are involved in almost everything that they see or do. While there are multiple ways that physics is used in a soccer game‚ this paper explores three parts and the physics that are involved in each one. The three parts that are going to be discussed are passing‚ heading‚ and throw-ins. These three can explain how physics can work from a soccer ball coming or going in each and every direction. Also‚ every

I started vacuuming‚ that took me at least 2 hours because I ended up vacuuming the entire house. I was sooo tired when I finished‚ I had 6 hours left before Jennifer Lawrence arrived‚ what should I do to impress her? I mean besides talking about physics? I decided I’d make some coffee for the two of us‚ while all of this happens I remember that the A/C turns on every 30 minutes for 30 minutes‚ so it is on for 12 hours a day‚ then I remember to wash my dishes‚ so I put them in the dishwasher‚ which

Behind the Curtain: The Process of Choreographing a Performance If you have ever gone to a ballet‚ musical or any sort of live performance‚ you most likely saw some sort of choreography. The art of choreographing is somewhat like writing. You have to plan and research‚ write an outline‚ create multiple drafts‚ receive edits and critiques from peers‚ and finally ending with a finished product to share with the public. Choreography can move the viewer through a storyline‚ portray different emotions

Germans used a tactic known as Blitzkrieg (Lightning War) to invade their enemies. This tactic enables them to quickly destroy their enemies. This tactic relies on Airplanes‚ Assault tanks and infantry all working together to catch the enemies by surprise. Without Airplanes the Blitzkrieg tactic wouldn’t have worked as well‚ as the Airplanes drop special troops near the cities to blow bridges and supply lines. The Planes then went on to attack the cities‚ causing chaos. Germany quickly went on to attack

** Atom and Introduction to Nuclear physics ** Introduction Alpha-particle scattering 2.1 Experimental set-up ➢ Alpha particle o is a high-energy helium nucleus with 2 protons and 2 neutrons. o has 2 positive charges. ➢ Gold foil was chosen since it has a high atomic mass. Thin gold foil‚ ~10-6m was bombarded by high-energy alpha particles. ➢ Angular deflections/ scattering of alpha particles were measured by observing

Experiment 1: Simple Harmonic Motion Dominic Stone Lab Partner: Andrew Lugliani January 9‚ 2012 Physics 132 Lab Section 13 Theory For this experiment we investigated and learned about simple harmonic motion. To do this we hung and measured different masses on a spring-mass system to calculate the force constant k. Simple harmonic motion is a special type of periodic motion. It is best described as an oscillation motion that causes an object to move back-and-forth in response to

Presentation In Physics Objectives: 1. To answer the following questions: What is an investigatory project ? Why do 4th year students make an investigatory project ? Why did we choose our investigatory project ? To defend our investigatory project. What is an investigatory project ? An investigatory project is also known as an experimental project and is one which is used to show how something might happen if certain conditions are added to it. It can also be used to investigate why
