Newton’s Laws of Motion in Modern Aircrafts - 1087 Words

The world today requires multiple ways of transport, especially over the Atlantic Ocean. During and before the 1900’s, transatlantic travels were very common and are mainly carried out via boats. However, due to the revolutionary change by the Wright brothers, in 1903, the creation of the propeller planes made shorter travel time between one country to another possible. As technology develops, the transportation of cargo and passengers via airplanes became easier and more efficient with the replacement of jet engines in July 16, 1949, by the famous inventor Frank Whittle (FindtheData, n.d.). The principles behind how a jet-engine powered aircraft works associate with many laws of physics, from Newton’s Law of Inertia to the Third Law of†¦show more content†¦Due to the high speed rotation of the fans and turbines in the engine and the incredibly high operating temperature, (Wickerson, J. 2011) the materials needed to sustain the dramatic speed and temperature a re highly expensive. Not only that, but the engines must have a low mass, so it doesn’t effect the total mass of the aircraft, meaning the funding costs will be incredibly high, an estimate of US$2 million. Continuing from that, is the high usage of fuel to power the engines, as they need to be powered constantly, than a fluctuating load. (Brain, M. 2000) Although the cost for the development of jet engines are expensive, it is very useful for transcontinental jet aircrafts, and it is worth the money to allow further developments, such as the increase in fuel efficiency, allowing a higher max endurance. Secondly, â€Å"air transport’s contribution to climate change represents 2%† (CleanSky, n.d.) meaning the Carbon emission is high. Each year, aircrafts traveling across the world produce an estimate of 628,000,000 tonnes of CO2 annually. Not only does aircrafts pollute the skies with harmful emission, but it also causes noise pollution. (Amin, Z. n.d.) These are caused by the jet engines, the consumption of the fuel, and the process of the air going through the fans and turbines due to Newton’s second law of motion, there are consequences towards the usage of aircrafts.

There are three laws in motion that explain movement, they are the Newton’s three laws o f motion named after Isaac Newton. The Newton’s first law states that an object that is a rest will stay at rest unless an outside force is acted upon it and an object that is in motion will stay in motion unless an outside force is acted upon it. This is also called as â€Å"inertia†Read MoreThe Phenomenon of Motion in Physics892 Words   |  4 Pagesthe word motion in terms of physics from ‘a simple movement’ to ‘a change in position, if acted upon by an unbalanced force’. In modern physics, motion is the change in position of an object with respect to its time and its reference point. Motion can be described as both scalar and vector quantity in relation to displacement, speed, direction, velocity, acceleration and time. If an object in not changing its position over time, then it is said to be in a stationary position.

In your own words explain why Albert Einstein considered Galileo to be the â€Å"father of modern science† Albert Einstein considered Galileo to be the father of modern science because of how many of Galileo’s discoveries have become the basis of today’s science. 2. Why did Galileo choose to use a ramp to perform his acceleration experiment? Technology during Galileo’s time was still quite primitive.

German technology advances in modern warfare were more of a danger to the world that many would like to admit. We are very fortunate that Adolf Hitler made the mistakes he made in the design and production of these advanced airplanes.

How Helicopters Fly http://science.howstuffworks.com/transport/flight/modern/helicopter6.htm Imagine that we would like to create a machine that can simply fly straight upward. Lets not even worry about getting back down for the moment -- up is all that matters. If you are going to provide the upward force with a wing, then the wing has to be in motion in order to create lift. Wings create lift by deflecting air downward and benefiting from the equal and oppositeRead MoreThe Following Chapter Discusses Background Information1685 Words   |  7 Pagesdesigns of rotary-winged aircrafts. Now known as the Da Vinci Helix, the design embodied the basic concepts of modern-day helicopters. Although it is unclear whether he built a successful model, the idea that a spiral wing device that turned fast enough to lift the device into the air was unheard of at the time [2]. Unlike conventional airplanes, rotary-winged aircrafts have a fundamental advantage in that lift and control are relatively independent of forward speed. Rotary aircrafts do not need a runwayRead MoreAerofoil Design Xflr56185 Words   |  25 Pagesprogram can also be used as basic tool to show the users what will happen when some variables like Reynolds number, the AOA of the wings and the speed of the aircraft are changed and how it will affect the results and lift generated.

In this analysis, the lift, drag, pressure profiles and their coefficients of the airfoils are been calculated using xflr5 program.

For example, physics explains why rainbows have colours, what keeps a satellite in orbit, and what atoms and nuclei are made of. The goal of physics is to explain as many things as possible using as few laws as possible, revealing natures underlying simplicity and beauty. Physics has been applied in many industrial fields, which include the air industry, construction industry, automobile industry, manufacturing industry and many others. All these industries
