Submarines
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 t
In 1954 the Navy made the first nuclear powered submarine. They called it, "Nautilus." When the submarine first went out, it broke all of the other submarine's records for underwater speed and endurance. "Nautilus" was also the first submarine to go under the ice at the North Pole. In 1908 Great Britain launched the first diesel powered submarine. There were a few advantages to using diesel. The advantages were that the submarines became more powerful, it was cheaper to operate, and the fumes were less dangerous than gasoline. After the invention of this diesel submarine all the submarines were diesel until the development of the nuclear submarine. 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. hat a submarine was used to attack another submarin
