Lighter than air

the study of physics a lot of the basics were put in place by Isaac Newton. Out of the 3 laws of motion he had declared the second law states that force equals mass times acceleration (F=ma). The Atwood machine is a machine that has a pulley in the air and a string running through the pulley, some kind of mass is suspended by each end of the string. When the suspended masses are unequal, the system will accelerate towards the direction of the larger mass. In this experiment, we used different masses

Aerodynamics is the study of properties of moving air, and especially of the interaction between the air and solid bodies moving through it. Our guiding question was “ Which design yields the Paper Airplane that travels the furthest?” For us to have a good plane we had to make sure that we took these types of aerodynamics into consideration, drag, gravity, thrust, and lift. Drag is the resistance against something when moving through the air. The next type is gravity, this will affect the item

Ford’s strategy will help protect the environment as a whole. Specifically, Ford is trying to improve the fuel economy for their consumers. As a result, CO2 emissions will be reduced significantly, which will improve public health and the quality of air. Other green efforts will help minimize its environmental impact through the conservation of energy and reduce pollution. This is an advantage because the company

transformed into helium II, also called superfluid helium, a liquid with unique physical properties. It has no freezing point, and its viscosity is apparently zero; it passes readily through minute cracks. Helium-3, the lighter helium isotope, which has an even lower boiling point than ordinary helium, exhibits different properties when liquefied. Helium is the second most abundant element in the universe, after hydrogen; however, it is rare on earth, primarily found mixed with natural gas trapped in

to the Soviets vast wealth in oil resources. In order to become a prosperous country with the best war technology, oil is one of the most necessary resources to have. Just like in Pearl Harbor, the Japanese targeted the oil, so the U.S could not get air domination. Another reason was that after the Russo Japanese War, Japan and the

Between all of the factors that outline the scientific studies such the theories, hypothesis and even law but what differences and similarities do they share? A scientific theory is usually said to be a well tested concept that explains an endless supply of observations. For example we obviously know that the Earth revolves around the sun and has been tested through observation and experiment which clearly cant come up with another explanation to contradict this theory. On the other end of the spectrum

Japan’s attack on Pearl Harbor could have not happened if a Mongolian Cavalry had never crossed the Manchurian Border in 1939. Just because of this small battle between Japan and Soviet Union, Japan was compelled to attack Pearl Harbor in December 7, 1941. But this battle is the most forgotten battle I have ever heard about. The battle of Khalkhin Gol was not even mentioned in the History class when we learned about Pearl Harbor, even though it is related. In this paper, I will cover how the battle

repairs and upgrades.Another cutting edge technology is using aluminum. Aluminum is lighter and stronger than steel, also aluminum doesn't rust. With aluminum being lighter that means the car gets better gas mileage. But if the the car gets into a wreck, either need to replace whatever is dange or pull dents with the special aluminum riveting tool and welding equipment.With service technician is turning more geeky than greasy a tablet computer is the most valuable tool in the shop.

buy one. Hybrid cars are extremely different than a gasoline car. Gasoline cars run off only gasoline, which produces more pollution that goes into the air. A gasoline-electric car, which uses both systems of gasoline powered and electric powered cars, emits less pollution into the air (Nice). Many people find it to be

measuring the weight with a scale, instead of comparing it directly with other masses. Weight is just a force while mass is a property (along with gravity) that determines the strength of the force (weight). An object on the Moon would weigh less than it does on Earth because of the lower
