Research Paper Instructions:

you can choose any topic relates to motions, Newton’s law of motion, gravitation, work, and energy. One page of research proposal is needed, and one page of bibliography.

REQUIRED RESEARCH PAPER: (25% of Final grade)

Students are required to research any of the topics covered in the syllabus or textbook and write a short, three-page, double-spaced, 12-point type (750-1000 word) paper on that topic, PLUS a one-page bibliography with at least three citations, on either:

1. a topic covered in the syllabus or textbook

OR

2. an instrument or device that uses the principles or topics covered in the syllabus or textbook 

You can look through the various syllabus or textbook topics and Google your heart away trying to find a topic that interests you. Then check to see what Wikipedia says about it.

What devices are included in the topic area? What physical theories are being used?

Clearly, this is NOT a true research paper, but you DO need to include a one-page bibliography including at least three (3) citations of Journal papers you have consulted as well as all the Web Site links you have reviewed in your search for additional information on the particular topic.

For example: If you selected a topic on the color of commercial light sources – you might decide to research light emitting diodes or fluorescent light bulbs or incandescent lights and compare their energy consumption at a particular light output level. Or, you might investigate the scientific principles behind an architectural success or failure.

In class we will review using Pratt’s Library research tools to find articles about your research topic.

Research Proposal
This paper seeks to define and describe the characteristics of a direct current (DC) dynamo, look into the historical innovations and ideas that led to the rise of the modern-day dynamo, explain the scientific theory behind the working of a dynamo, and analyze the limitations and uses, historical and modern, of a DC electrical generator.
The Dynamo
Definitions
A dynamo is an electric generator that facilitates the conversion of mechanical energy to electrical energy in direct current (DC) using a commutator. A distinction is made between a dynamo and an alternator. An alternator is an electrical generator that also converts mechanical energy to electrical energy in alternating current (AC).
According to Hawkins and Wallis (1893), the dynamo is an electrical pump that generates an electromotive force and maintains it when an electric current flows under pressure. The word dynamo is coined from the word ‘dynamis’, which in Greek means force or power. The word was coined in the 19th century by an English scientist, Michael Faraday, who is widely credited for his contribution to electrochemistry and electromagnetism. (Williams, 1965).
History
In 1832, the first dynamo was created by a French scientist, Hippolyte Pixii, using a commutator. Interestingly, he also built the first alternator by accident (Edison Tech Centre, 2011). Thirty-five years later, in 1867, two scientists, Werner Von Siemens and Charles Wheatstone improved on Hippolyte’s work and built a powerful and far more useful dynamo that used a self-powered electromagnet that was stronger compared to the weak stator magnet in the original design. The 1870s brought further advancements and continuous improvements to the design of the dynamo. In 1871, a scientist called Zenobe Gramme improved the design to allow the dynamo to be used in many commercial applications. Later on, in 1876, Charles F. Brush developed the most efficient dynamo that had ever been created up to that point. The 1880s marked the rise of the electrical age. In 1886, some inventors like Nikola Tesla and William Stanley worked on their designs of AC systems and generators based on Siemens and Ferranti generators. In 1890, the design of the generators was largely improved, and most of these generators are u...
