- Our catapult was a little inaccurate because the position of the arm of the catapult was crooked.
-Our catapult was too big
- By ignoring air resistance, our calculations are off.
If we had stayed within the specifications of 1 cubic meter, our catapult would have been better. Also, to make the catapult better in the future, we could have made a better guidance system for the arm.
Although the catapult was bigger than the specifications, our catapult performed very well in precision and accuracy. We were amazed by its performance and were happy about how it came out. This was a very fun project to work on.
