Bottle Rockets :: essays research papers

A rocket in its simplest form is a chamber enclosing a gas under pressure. A small opening at one end of the chamber allows the gas to escape, and in doing so provides a thrust that propels the rocket in the opposite direction. Newton’s laws can be used to explain this his laws in the simplest terms can be explained like this: First law- Objects at rest will stay at rest and objects in motion will stay in motion in a straight line unless acted upon by an unbalanced force. Second law- Force is equal to mass times acceleration. Third law- For every action there is always an opposite and equal reaction. For the rocket to launch it needed to be propelled by something, for our rockets we used regular air and compressed it. Upon releasing the stopper Newton’s first law went into effect which states that for something to move a force must act upon it in this case the gas moving out of the bottle. When the stopper was pulled the pressure in the bottle forced its way down, which applied the force to start the motion of the bottle. His 3rd law can also explain this because the water going down forces the rocket in the exact opposite direction the water goes. Which is why one time when we shot the rocket it flew at an angle. Also it shows why the launchers had stoppers, because if they didn’t the cork wasn’t strong enough to hold that pressure and would cause the rocket to begin flight prematurely. His second law can be used to describe how high and fast the rocket will go. If you wanted it to go really high and fast you would just pump more pressure into it then if you didn’t want it to go that high. You can determine how much force is needed by multiplying the mass by the acceleration.   Ã‚  Ã‚  Ã‚  Ã‚  Our rocket was fairly decent the only problems were that the wings were not completely stable. Our egg survived in the capsule we built and one other egg even survived with out being in a capsule at all.

Origin of life Essay

In the summary given, theory of life is said to have risen from the primitive earth’s atmosphere. The atmosphere of the early earth is said to have many carbon dioxides but no oxygen. These carbon dioxides will act as reactants in order to create much more complex organic substances such as proteins, carbohydrates lipids, phospholipids, and nucleotides. The said substances are well known as the building blocks of life. This is the evidence that supports their claim that life originated from the gases present in the early earth’s atmosphere. Also to support their claims, an experiment during the early 1950’s would confirm that it is true that simple carbon based compounds can naturally be created under the environment of the primitive earth. In other readings, the early life is said to have also talks about the building blocks of life. The Panspermia theory proposed that these building blocks of life would have originated outside of the earth. These building blocks or the ‘seed of life’ might be scattered around the galaxy or even the universe. Also the same as the summary in piecing it together, the panspermia theory suggests that whenever conditions are met, the building blocks of life will grow and develop. The only downfall of the theory is that, since the building blocks of life came from outside the earth, then there is a great possibility that other life may form from outside of the earth. Evidence of this theory is that, a certain bacteria were discovered in the earth’s upper atmosphere. What’s interesting with the discovery is that the bacteria were similar to the bacteria found in the earth. The bacteria might brought by the space crafts that left the earth. But still, there is a probability that the bacteria would have evolved from outside of the earth. Unfortunately, this theory is lacking in evidence. Some scientists are still on the verge of research in order to prove that their claims were right (Backman, 2007). The summary has a basis about its claims of the origin of life. But problems arise. The origin of the earth is still not established very well. It is said in the summary that substances from the early earth will evolve but the existence of the early earth is not yet been proved. Both the theories lack evidence to support claims of the origin of life.
