What is a Cannon?

The cannon is a type of artillery, usually large and looks like a cylinder, that uses gunpowder or other usually explosive-based propellants to launch off a projectile over a distance. Cannons vary in caliber, range, mobility, rate of fire, angle of fire, and firepower. Different forms of cannon combine and balance these attributes in varying degrees, depending on their intended use on the battlefield. The word cannon is derived from several languages, in which the original definition can most of the be translated as a tube or cane. In modern times, cannons has fallen out of common usage, usually replaced by "guns" or "artillery", if not a more specific term, such as "mortar" or "howitzer".

What we thought would happen.

We concluded that our hypothesis would be right. We decided that our cannon would make a perfect parabola but because of the coldness and the wind the day we decided to shoot the cannons NONE of them worked.

Materials of our Cannon.

Materials

1. We obtained two empty tennis racquet bottles with caps.

2. 18 inch peice of tape.

3. Scissors.

Before we started we thought out how we wanted our cannon to look and what angle would affect the offspring of the fire. We decided that a 34 angle degree would be best for our cannon to work in the way of percision. The pressure , temperature, and volume played a big role in our decision of what our cannon would look like.
