Goal: How does the change in distance pulled back on the rubberband effect the distance of the paper.

Procedure: 1. Fold 1/8 of a piece of paper into a small square. Put some tape on it. 2. Wrap a rubberband around a[|slingshot.JPG] circle to create a slingshot. 3. Put tape on the handle at 5cm, 10cm, and 15cm. 4. Put meter sticks down in a line for 18 meters. 5. Put the paper on the rubberband. 6. Pull the rubberband back and shoot it. Shoot from each distance three times. Data:

5cm pulled back

1. 10.12m 2. 10.8m 3. 10.3m

10 cm pulled back

1. 13.5m 2. 14.31m 3. 12.77m

15 cm pulled back

1. 18.31 2. 17.1 3. 17m

Conclusion:

The farther back you pull the rubber band, the longer the distance it travels. We used one piece of paper and just changed the distance that we shot it. At 5cm the average was around 10.7m. When we pulled it back 10cm the average distance was around 13.9m. When we pulled it back 15cm the average distance was around 17.5m. As you can see the farther back you pull the rubberband the farther the paper is shot. The farther back the rubberband is pulled the more tension is created. With more tension, the velocity of the paper is greater. There is a higher amount of force projecting the paper from the rubberband. There are many posible sources of error that could occur also. The angle at which you project the paper could be different. That can affect the height of the paper and change the distance a little. Pulling back the rubberband straight is another source of error. When pulling it back you might pull it to the side. This can effect the flight pattern. The paper might spin and air pressure will effect it. It might tail to the left or right effecting the distance. It wont project to its full potential if its not launched straight.
