Rockets have been around thousands of years ago but they never worked the best. The earliest solid rocket fuel was in the form of gunpowder, and the earliest recorded mention of gunpowder comes from China late in the third century before Christ. The Chinese put gunpowder in bamboo tubes and threw them into fire in hopes to make loud enough sounds so that it would scare the evil spirits away from them. Some of the bamboo tubes were not sealed properly and instead of making loud sounds it shot off in fire flying through the air. One clever observer saw this and started to make tests about rockets and that was the first discovery of rockets. It later was used in China’s war tactics. In 1232 AD they built the first rocket and it flew around the room. After seeing the Chinese rockets other civilizations started to use the rockets in their war tactics. They used “Fire Arrows” for wars. It was hard to control and they did not know if it would hurt them or the enemy. The first rocket to get to space first was the Russians but America got to the moon in July, 20 1969. That was one of the most historical moments in America’s History.
Rockets use Newton’s Laws of Motions. First Law states that objects at rest remain at rest and objects in motion remain in motion in a straight line unless acted upon by an unbalanced force. Second Law states that force equals mass times acceleration. Third Law states that every action there is an equal and opposite reaction. Rockets use the first law of motion by using its massive force of rocket power to lift the object from its rest. The second law is just how much force is needed to lift the object from the ground. It uses the Third Law is that the rocket power force going downwards has an equal and opposi...

...st a few decades or so. It took a long time for the concept to turn into reality. The very first successful demonstration of the solar sail didn’t come until 2010. It was by Japan’s Ikaros Probe deployed a 46 foot wide sail and became the very first spacecraft to ever cruise through space on the backs of photons. NASA went along with the Japanese five months later, launching the tiny NanoSail-D demonstrator to orbit Earth in November 2010. The NanoSail-D unfurled its sail in January 2011, then circled the planet for eight months before burning up in the atmosphere. Other projects by NASA and other companies loom on the horizon, building momentum for the technology. A big milestone should come in early 2016. That’s when NASA plans to launch the largest ever solar sail to space. One day NASA will get there and then space flight will be easier and more cost-effective.
Cost management plays a major role when maintaining profit margins. Management must be able to find in which areas of a business costs must be reduced and the consequences that such reductions have in the overall company. In some situations management must change the way the work is being done in order to decrease costs while in other cases changing one supplier for another might be enough, in both situations a tradeoff will occur and the consequences will impact the company as a whole.
Newtons second law can be indentified more easily using the equation F=ma. This is an equation that is very familiar to those of us that wish to do well in any physics class! This equation tells us many things. First it tells us the net force that is being exerted on an object, but it also tells us the acceleration of that object as well as its mass. The force on an object is measured in Newtons (I wonder where they got that from). One Newton is equal to one (kg)(m)/s^2. For example, if superman pushes on a 10,000kg truck and it is moving at a rate of 2m/s^2, then the force that superman is exerting on the truck is 20,000N. For those of us that wish to move on in the field of physics, Newtons second law (F=ma) will forever haunt us!
The Soviets took a lead by launching the first successful satellite into space. On October 4, 1957 the Soviets launched the first successful satellite into orbit. It was called Sputnik I and it successfully entered Earth’s orbit. This first success started the Space Age. The Soviets successful launch shocked the whole world, giving the Soviet Union the respect for putting the first man-made object into outer space. The Americans successfully launched their first satellite four months after Sputnik I, called the Explorer I. The US would have had the first satellite in orbit if they were allowed to use military rockets from the beginning. But, Eisenhower was worried he would be called a warmonger if he used military rockets for launching a satellite into orbit. He told the sci...
Many people are amazed with the flight of an object, especially one the size of an airplane, but they do not realize how much physics plays a role in this amazing incident. There are many different ways in which physics aids the flight of an aircraft. In the following few paragraphs some of the many ways will be described so that you, the reader, will realize physics at work in the world of flight.
Newton’s 2nd Law of Motion states that acceleration is directly proportional to net force when mass is constant. This experiment dealing with variable forces has as its objective the verification of this law. In this experiment this law is tested for verification in straight forward way. Through the use of a Force Sensor and an Accelerometer, data collection of observations and measurements that a force exerts on a small cart along with the cart’s accelerations are to be determined. The sensors’ measurements will be employed to give meaningful relationships between the net force on the cart, its mass, and its acceleration under these conditions. The resultant measurements revealed will verify and determine the force and acceleration relationship as stated by Newton.
In this paper you will learn so much about rockets you can become a rocket specialist. Many may ask how do rockets work? Many will respond that they are pushed against something but that is wrong. Since rocket's main purpose are to travel in space where there is nothing, not even air they can not rely on “something” to push themselves against in space. This is the right answer to how rockets work; Rockets use fuel, they burn the fuel and it turns into hot gas.
NASA, National Aeronautics and Space Administration, was formed in 1958 shortly after the Russia launched of Sputnik and the R-7 ICMB Rocket. The administration was formed to research and progress anything that had to do with space, flight, or other aeronautics. Just over a year after the launch of Sputnik, on October 11, 1958 NASA launched its first rocket: Pioneer I. The primary purpose of this rocket was to measure magnetic fields around the Earth. Although the Sputnik projects had many of the same capabilities, the US having finally launched a rocket meant that they were really in the race.
Planes have developed immensely through the years. The Wright brothers developed the first plane in 1903.
Physics is involved in everyday life and can be an essential explanation for how things work. Being a lacrosse goalie involves physics concepts and proves how they apply to every movement that is made on the field. To better understand the physics of a goalie, you must understand how Newton’s Three Laws of Motion work; Inertia, force equals mass times acceleration, and equal and opposite forces, as well as another law torque and leverage.
One thing that helped build a space rocket was a V-2 rocket built by the Germans during WWII. Throughout the years the V-2 rocket turned into the Saturn V rocket. The Saturn V was a rocket NASA built to send people to the moon. The Saturn V rocket was 363 feet tall and about the height of a 36-story-tall building. The Saturn V that launched the Skylab space station only had two stages. The Saturn V rockets used for the Apollo missions had three stages. Each stage would burn its engines until it was out of fuel and would then separate from the rocket and then the next one will start. If it wasn’t for the V-2 and German scientist, von Braun the USA would probably have not traveled to space. The USA sent astronaut John Glent to circle the Earth in 1962 to retaliate the launching of Sputnik. In 1969, a milestone was reached when the USA sent astronaut Neil Armstrong to the moon. The technology on the ship that took Neil to space was equivalent to a basic calculator built in 1980. They took a 64Kb computer (the moon lander) with them to space. It had approximately 64...
Flight uses four forces: lift, weight, thrust, and drag. In a nutshell; so to speak, an airplane must create enough lift to support its own weight. Secondly, the airplane must produce thrust to propel itself. Finally, the aircraft must overcome the drag or the force of resistance on the airplane that is moving through the air. All four of these forces are vital and necessary for an aircraft to move, takeoff, fly, and land.
Long ago rockets were used to launch fire crackers into the air in china, now they are used to travel beyond the stars. Rockets became bigger and much more manageable which instantly made them beneficial to U.S. and the Soviet Union’s space race. The Soviet Union was the first to orbit around the world while the U.S was the first to put a man on the moon. After World War II rockets were also used specifically for launching satellites in orbit, because of this we now have gps, we can predict when the weather changes, when storms are coming, make international calls, for the most part, even use our cell phones. The final technological change of the 20th century are atomic weapons. During World War II the atomic bomb that was dropped on Hiroshima proved to be lethal to everyone. Humans now had the ability to destroy an entire country by just the push of a button. Powerful countries like the U.S and the Soviet Union realized the deadly future ahead and made it their goal to never have another world war. Atomic science on the other hand led to a controversial process of producing energy called fission, which is now used to power submarines, electricity, and aircraft
In 1957 the Soviets used a missile to launch a satellite, Sputnik 1, into orbit around the earth. The arms race then became a space race as the United States rushed to launch its own satellites, some for military purposes.
Sir Isaac Newton is the man well known for his discoveries around the term, Motion. He came up with three basic ideas, called Newton’s three laws of motion.
Projectile motion is the force that acts upon an object that is released or thrown into the air. Once the object is in the air, the object has two significant forces acting upon it at the time of release. These forces are also known as horizontal and vertical forces. These forces determine the flight path and are affected by gravity, air resistance, angle of release, speed of release, height of release and spin
