This experiment was done to see what variables (weight, wind, friction etc.) affected the apogee of the rocket. The class did this by recording everyone's rocket weight and compared them to the apogee's after they had been launched. Due to different variables, the apogee might be affected in a variety of ways, one being the weather. After the class found all of the data, it was compared and analyzed for any patterns. The rocket had different forces acting upon it during the flight stages. The…

CMRJ341 Professor Jennifer Bourgeois October 18, 2015 Impact radial fracture lines ends shortly after the earlier impacts. In this case, bullet (C) was the first shot followed by (B) And lastly (A). In order to figure out the order of bullets is figuring out the radial fractures is looking at the initial fracture. Bullet fractures are round and has the same shape as a wheel. Fractures Also connects in the shape of a spider web. Then you have to figure out which side the fragment is facing in…

Electrons are small negatively charged particles that are found in the electron cloud of an atom. These electrons repel other negatively charged particles and are attracted to positively charged particles. They are important because they play a major role in creating chemical bonds between atoms and contribute to its mass. A scientist by the name of Robert Andrews Millikan won a Nobel Prize for his study and finding of the charge of an electron. His findings greatly helped the scientific…

From the times of the ancient Greeks to modern day, scientist have argued the concepts behind matter. During the time of Aristotle, philosophers created scientific theories based on logic alone, eliminating all scientific evidence. This is when Democritus proposed his theory. Later, Dalton proposed his theory after completing experiments about matter. Democritus's theory was the theory of atomos. He claimed that atomos were particles so small that they could no longer be divided. Democritus…

One of the most beneficial attack strategies in volleyball is the execution of a fast paced, downwards directional spike. A spike is proven to be one of the most effective shots in volleyball due to its force and difficulty for the opposition to return the shot. Through developments in modern technology in sport, biomechanics has become one of the most influential evaluative sources for skill analysis aiding improvements in sporting performance. A video analysis of my volleyball spike will be…

Introduction- In theory, parachutes work because of the force of gravity. Gravity is a force of attraction between two objects, that is highly affected by size and proximity (gravity will have a stronger pull if the object are larger and close together). Gravity also differs from the mass of an object the more mass an object has the more gravity it will exert on the objects around it. When looking at really large masses, like the earth the gravitational pull becomes much greater because of its…

Air hockey is a fun, mindless activity for everyone to play but do you really know the complex science behind it? Air hockey involves concepts from Newton’s three laws of motion. The science behind air hockey is all based off of Newton’s laws. The air hockey table allows the puck to glide easily and certain forces are required to move the puck, stop the puck, and accelerate the puck. Also, for every force applied on the puck, there is always an equal and opposite reaction. The next few…

This experiment, created by the students of the class, went relatively well. In this lab, we teste the theory of the conservation of energy. The kinetic energy at the bottom of the ramp should equal the potential energy at the top of the ramp without regard to the path taken. Thus, for method 1, the equations for kinetic energy (1/2mv²) and potential gravitational energy (U_g=mgh) were used. For the second method, the concepts and formulas for constant acceleration was used in conjunction with…

Script Are reusable rockets a sustainable possibility for the future? What are rockets? Rocket technology is extremely wasteful, and being a one shot wonder, they show no promise of a sustainable future. When a rocket is launched, it is propelled based upon newton’s 3rd law of motion; “For every action, there is an equal and opposite reaction.” This is done by using on board propellant which is then used to create thrust from a rocket engine, by ejecting thrust in the opposite direction to…

Who is Albert Einstein? Einstein was a genius man who was very under rated until his later years of life. He invented the theory of relativity, that is incredibly famous now, and is considered one of the most influential person for the 20th century. Einstein was born in 1879 in Germany. He grew up in the middle class inside a Jewish family. Einstein had a father who was an engineer and a mother who was a regular housewife. Einstein had two siblings one brother and one sister that was born two…
