I chose to do my Physics final on submarines. I chose it because when I was a kid I was really interested in submarines. Also I wanted to learn about the people that invented them.
The first submarine that was made was a wooden rowboat that was covered with a waterproof cowhide. The man that first built it was named Cornelius van Drebble. He showed off his invention in England, the year was about 1620. They called his submarine, “Father of the Submarine.” After that a lot of scientist were trying to make submarines. Most of them were not used until the Revolutionary War of America (1775-1783). When that war was going on a man named David Bushnell, that went to Yale College, designed a submarine that he called, “The Turtle.” It was a one-man submarine that was powered by a crank that you had to turn by hand. When you turned the crank that would make the propeller spin so you would move. They tested out, “The Turtle” in the New York harbor, but it failed. That was the first time that a submarine was used to attack another submarine.
The third submarine was built is by a man named Robert Fulton; he was an American inventor. He designed a submarine named the, “U.S.S. Nautilus.” It was a copper-covered submarine that was 21 feet long. He tried to sell his ship to both France and England. In his demonstration it sunk many of ships, but they still did not want to buy it.
In the Civil War (1861-1865) a submarine named, “Hunley,” was the first submarine to sink a ship in wartime. It had a long pole on its bow, at the end of the pole there was a piece of explosive. When it tried to sink the submarine named, “Housatonis,” it succeded, but it also sank itself.
The next submarine that was made is by an American inventor named John P. Holland. He made a submarine that was 53 feet long. It used gasoline...
