Hypothesis

We decided to use a 45 degree angle for our cannon so that it would go high but not too high so we would maximize the distance. We predicted that our cannon would make a parabola and shoot as far as 5 feet.

Cannon Results

Our cannon was not successful. Possible reasons for this could be the temperature or the ethanol. According to Gay Lussaccs law temperature and pressure are directly proportionate, and due to the low temperature there was low pressure. To be continued... We will reconstruct our cannons and launch them in April when the temperature is higher.


Launch Formula- R = Vo^2sin2O/g O=degree

0=Vo^2sin(2O45)/32.2 ft/sec^2

Vo^2= 0

Early 1900's

When you think of cannons you often think of them being used violently. In this case however the cannons were used during a celebration. During the early 1900's, many people would set off cannons as well as fireworks during the fourth of July. This was a tradition done by many americans till it became a harm more than anything. Many people were killed from these explosions and the setting off of cannons even for celebrational purposes was prohibited.

1800- Civil War Cannons

Many cannons were shot during the Civil War. The Civil War took place from 1861 to 1865, mostly on the eastern half of the United States, and 618,000 Americans died fighting for freedom. Cannons were used frequently targeting charging forces from a distance. It took alot of people and time to load a cannon ball into the cannon. Most cannon balls during this time were made out of steel, bronze, and iron and they weighed anywhere from 12 and 32 pounds. Naval and siege cannons, including Dahlgrens and Rodman smoothbores, were among the heaviest and most powerful, ranging up to 2,000 yards and the shells weighed from forty five to ninety pounds. The favorite artillery piece used and liked both by the union and confed. was the Napoleon. The reason being was they were very powerful, but at the same time light and portable. Overall cannons were he most deadly and powerful artillery used during this time.

1700- Trebuchet

During the 1700's cannons were used to protect from invasions from other countries. The Trebuchet, which is the third type of engine, and the largest of the three catapults. The trebuchet consists of a long arm, counterweighted to provide sufficient spring, with a leather sling on the opposite end, into which a large stone or another object of substantial size and weight would be placed. Cannons weren't frequently used in North America prior to The French and Indian War, the use of cannon and other artillery proliferated.
