Range Formula

G=32.3 (feet/per second)

V=Initial Velocity (What We Find

(Theta)= Launch angle in degrees

R= Launch Distance

Procedure

1. We took the end off of one of our cans.

2. We put the top of the can on the end of the can that was cut.

3. Replaced cut end to can with top of end.

4. Tape it securely

5. Cut an arch out of other can

6. Lay can on top of cut can.

7. Tape it on it securely.

Test Firing

Cannon Firing

1. Cannon construction design choice?
Answer: For a stable base, higher concentration of gas, and a smaller volume for more pressure.

2. Launch angle choice?
Answer: We picked a 40 degree angle for a balance between initial velocity, and altitude.

3. Expected results?
Answer: We thought the back end would blow off, because it was lose and not very secure.

4. What would you do differently?
Answer: Secure the back end, and the base.

5. Record distance your cannon shopt the nerf ball.
Answer: 0 feet.

6.Determine initial velocity of your firing
Answer: R=0

The History of the Cannon, in Modern Times

The peak of the design of the cannon is right now. From cannons that took 60 oxen and 200 mean to pull, and could only fire about 8 times a day, to now, when we have mobile cannons that can move 40 Miles per hour and bombard for hours on end. "Modern artillery" is classified as either firing an explosive shell, or a rocket. The first "modern" artillery unit is considered to be the "French 75 of 1897" with its cased ammunition, effective breech-loading, modern sights, and self-contained firing mechanism. It was considered to be the most effective artillery piece of the era. At that time, now artillery pieces have advanced further.

The History of the cannon, in 1700's-1800's

The cannon developed much more in the 1700's and 1800's than it ever did during the middle ages. The designing and engineering of artillery became a large movement and one of the men who made a large contribution to it was Jean-Baptiste de Gribeauval. He created a "standard cannon". A cannon that could interchange parts and be replared very easily because it was uniform. Another major advancement in cannons was the Flintlock mechanism. It is much safer more reliable and faster than the former way of igniting the cannon. The last major advancement in this time period was the "Rifled cannon" some firearms had been rifled before, but the technology for rifling a cannon did'nt exist till the 19th century.

The History of the cannon, in Pre 1700's

The first documented use of Artillery in war was during the Middle ages. The Chinese developed it and was first used by Han Shizhong when he was capturing the city Fujian. The first developed "Supergun" was created by the Turks when they took the city Constantinople. It had a 762 mm bore, and fired 1500 lb stones. The Europeans artillery developed during the "100 Years War". One of the drawbacks of the cannon during this time, was that it was'nt very mobile, so most of the time they were used in defending castles. The leading factor in a battle was still the infantry due to the fact that cannons were unreliable and slow, and could be easily overrun by an enemy advance.
