Light is an electromagnetic radiation that can be detected by humans. Electromagnetic radiation happens in an extremely large range of wavelengths from gamma rays to radio waves. Within that spectrum the wavelengths visible to humans are few. Light is very difficult to define, in the sense that scientist have been arguing weather light is a particle or a wave. Many experiments have been done to proof weather light is a particle or a wave. The truth is that light sometimes acts as a wave and…

When they round the brow of the first hill, the force of gravity makes them hurtle energy as well. Even the rattling noise the rollercoaster makes uses up some of its energy. The cars lose more and more of their original energy the longer the ride continues, and, since the cars have no engines, there's no way of replacing it.…

A scale model parachute will be designed and constructed to fall safely for the attached LEGO man to survive the parachute will provide enough air resistance to counteract gravity. One reason there is science in this problem is if the parachute goes to fast and kills the LEGO man to make the parachute go slower the parachute would have to be improved. Also, if parachute would be improved based on things such as how to make the air resistance greater making the parachute slower. Another, things…

Hatch (1998) states that Isaac Newton was born in January on the 4th of the year of 1643. Nussbaum (2014) mentions that Isaac was a top student and he went to study at university of Cambridge at the age of 19.Issac needed to be a top student to being able to study what he did at Cambridge, this allowed him to receive a degree and then work hard, then be named famous. In the year of 1665, Newton started to begin to create a mathematical theory that gave him a lead to build on the development of…

Sir Isaac Newton was a scholar, a mathematician, a scientist, and a professor. He created the 3 laws of physics and came up with one of the most famous gravity equations in history and more. This paper will explore his life, his achievements, and his studies, throughout his long lifetime. Sir Isaac Newton was born December 25th, 1642 in Woolsthorpe Lincolnshire, England. Two months before Isaac’s birth his father passed away. At 3 years of age his mother remarried and moved away leaving Isaac…

The purpose of this spectroscopy experiment was to determine if the spectra matched the electronic transitions that occur in the hydrogen atom among several other atoms. We used the Bohr model of atomic structure to determine the orbit numbers that correspond with the spectrum emitted by the hydrogen atom. The Bohr model states that electrons will never be found in between states, but rather completely in one state or the other. We used this model to determine the initial n value at which the…

Sir Isaac Newton was an English mathematician, astronomer, theologian, and physicist who is widely considered as one of the most powerful scientists of all time. He was also a key figure in the scientific world. He was born January 4, 1643, in Woolsthorpe, England, United Kingdom. Newton actually studied for a degree in law. Isaac was enrolled in Kings School in Grantham, a town in Lincolnshire. Sir Isaac Newton died March 31, 1727, in London, England, United KIngdom. SIr Isaac Newton is mostly…

Analysis/Discussion: This graph above shows that different heights does affect the speed of a shuttlecock. On the x axis, the data is the height of where the shuttlecock is dropped from, while the y axis is the average speed (m/s). The height where the shuttlecock is dropped increases, as the average speed of each height increases as well. The result of the graph is shown that the line keeps on increasing even if it is not a straight line graph. These results support my hypothesis, which states…

Motion Down an Inclined Plane Andrew Park Ms. Jatindranauth SPH 3U7-A September 28, 2017  Introduction The purpose of this lab is to determine the effect displacement has on the final velocity of a trolley on an inclined ramp. What is hypothesized is that as the distance the trolley rolls down decreases, the velocity should decrease with it. Also, because the trolley should uniformly accelerate, the standard equations of motion can be used to calculate many different variables (one such being…
