The history of hot air balloons starts in the Asia. Literary references in China date back to 180ce and cite Chu Ko Liang as the inventor of lighter than air flight (1). Early unmanned balloons were used in China as military signaling lanterns (2). Today ethnic Chinese communities celebrate the end of the Lunar New Year Holidays (3) by launching small hot air balloons ( known as Kung-Ming Lanterns ). The first recorded mathematical description of buoyancy (and thus hot air balloon behavior) was
factors are air resistance, shape, and weight (PhysLink). For example, a piece of construction paper, crumbled up, with some weight attached, and no air resistance will fall faster than a piece of printer paper, flat, with no weight attached, and wind pushing against it will. That can be figured out with simple common sense. The only two factors that really matter in this instance is the weight of the paper and the amount of air resistance. However, it takes a lot more thinking than just weight
better at coming up with new things. Guns, as a result of this, have gotten bigger and more destructive by each and every decade. Especially when it comes to machine guns; there are many different kinds with different aspects that make them better than guns of yesterday. This is my list of the top ten machine guns in the world. Enjoy. 10. XM307 ACSW Advanced Heavy Machine Gun This gun, XM307 ACSW (Advanced Crew Served Weapon), is a belt-fed machine with the capability to use smart shells and grenades
forces came in the form of air resistance and gravity. Procedure I chose to see what the effects of the weight the parachute had to support would have on the rate of its descent. My original prediction after some general thinking was that the heavier the parachute was, the faster the parachute would descend. I believe this to be totally true as it is a logical thought process; a feather falls slower than a hammer indicating heavier objects fall quicker than lighter objects. Also the aerodynamics
and the retort char. The match light brand is a small, square briquette with lighter fluid already infused into the briquette, allowing it to light instantly. One of the distinctive features which make it a better charcoal is the new innovative air flow method. The match light brand is the only square Kingsford charcoal with grooves on each side. The grooves maintain the optimal size and increased surface allowing air to flow better giving you a fire that burns longer. There are more edges to catch
ultimate dream to defy gravity and to be able to fly freely in the skies like a bird. Because of that dream, as early as 400 BC, humans had been experimenting with the idea of flying when a Greek scholar built a wooden pigeon that flew through the air. many after him had tried to fulfill that dream but failed , some of them succeeded but failed to sustain the flight , some even succeeded in sustaining the flight but failed due to unforeseen circumstances as their flying machines failed to live up
Nanotechnology. Nanotechnology is basically “an extension of existing sciences” (M.H. Fulekar 2010), only at a much smaller, nano, scale. Nanotechnology is the understanding and controlling of matter at sizes of roughly 1 to 100 nanometers, smaller than a strand of human hair, which is nearly 80,000 nanometers thick. figure 1 Using nanoscale science, phenomenal engineering, technological, and medical ideas, it covers a whole range of various developments. Although it contributes to many areas of
case is heavier it will have more gravitational pull pulling it down, thus increasing the speed. I also predict that the lighter the paper case, the quicker it will reach its terminal velocity. This is because to reach terminal velocity, the air resistance has to be equal to the accelerating force, if the accelerating force is less, then it should take less time for the air resistance to become equal to it. MY PRELIMINARY EXPERIMENT: For my preliminary experiment, I did the experiment,
destroyer ships. The building of faster, lighter, and more mobile aircrafts was a huge goal for both sides of the war. Especially to Hitler who used the Tausendfussler (Millipede) in his Luftwaffe air force. The upgrades to planes allowed for Hitler to bomb cities he invaded and it gave him astonishing success to his blitzkrieg strategy. Moreover, with the new upgra... ... middle of paper ... ... made Germany very effective. Now with tanks and planes being lighter and more mobile militaries were able
Gravitational Pull and Parachute Investigation Aim The aim of the experiment is to investigate how each of several different weights of varying mass attached to a parachute in turn can influence the gravitational pull and air resistance forces acting on it, consequently affecting the time it takes to reach the ground when dropped from a specific height. Preliminary Work Forces are measured in Newtons (N), named after Isaac Newton who invented this unit. We cannot see them but instead
I need matches. However, what if I use them all or they become wet? Therefore, I posited, “Maybe I should have a lighter instead, or as a backup.” This gave rise to the question, “What if the flint breaks or the fluid leaks?” The answer was easy, or so I believed. I needed a magnesium fire starter. But what if I wore down the magnesium bar? It seemed “overkill” to have matches, lighters, and magnesium bars. My search for an answer that didn’t involve a shoebox full of gear brought me to the Fire Piston
Transportation is one of the basic necessities of human civilization. If there is no transportation on land, sea, or air, there may not be communication between human beings on this planet. But there are also side effects of transportation, which includes pollution. Pollution means the harmful wastes produced by humans which damage our environment in many ways. The fast population growth rate of humans means that the necessity for transportation vehicles is also enormously increasing. Studies have

It obtains its buoyancy from the presence of a lighter-than-air gas such as hydrogen or helium. The first airship was developed by the French, called a ballon dirigible, it could be steered and could also be flown against the wind
lower amount of air pollution, as well as a lower risk of affecting the climate through global warming. There are three main kinds of nuclear energy, nuclear fusion, nuclear fission, and radioactive decay. This report will explain how nuclear fusion works, as well as explaining the advantages and disadvantages of nuclear fusion. Nuclear fusion occurs when two or more elements are fused together. Nuclear fusion cannot be used with elements that are heavier than iron, only lighter elements are used
Classification of Compressors A Compressor is a machine that compresses the air or another type of gas from a low inlet pressure (usually atmospheric pressure) to a higher desired pressure level. A Compressor increases the pressure of the air by reducing its volume. Work required for increasing a pressure of air is available from the primary mover driving the compressor. Usually, electric motor, internal combustion engine or steam engine, turbine etc. are used as prime movers. Compressors are similar
In order to reduce the consumption of energy and also for avoiding the air pollution, requirement of more fuel efficient automobile or vehicles are in demand and it is big challenge for automobile industries. There are various unique characteristic of aluminum for example excellent formability properties; higher strength & stiffness in respect of weight- ratio, properties of recyclability and most important good resistance against corrosion and it must be note down that these properties of aluminium
Ford 427 FE model engine was intentionally made for drag racing. The frame is large but,light weigh for a better performance. It weights between 120 and 195 pounds depending on the materials it is constructed of. The rear end is lifted for better air flow( super motor sports ) .The engine is present in Thunderbolt, Galaxy, and Fair lane ( ford motor Co ) This engine has the ability to reach a speed of 185 miles per hour. It also has overhead cams causing the engine to move faster. It would have
summer rains are called ordinary thunderstorms, or air mass thunderstorms. They form when warm, humid air rises in an unstable atmosphere. Warm air cools down as it rises, and once it becomes colder than the air around it, it will begin to fall back down. In an unstable atmosphere, the temperature of the surrounding air decreases faster with height than the temperature of the rising warm air. This causes the warm, moist air to continually be warmer than the atmosphere, and continue rising to large heights
Nearly every person in the world uses salt or some form of a salt as there are many salts in the world. In America alone we use a lot of salt every day we are one of the top salt using countries in the world. Salt has a part in many things in everyone’s daily lives. Salt has many important things to it such as its crystallization, what salt is and ammonia. Each type of crystal has its own properties and shapes. Crystals are an organized arrangement of atoms and molecules. The atoms sodium (Na) and
