Last week we launched catapults in class. My groups catapult averaged a distance of about .5 meters. Building the catapult we thought it was well built and would have gone a farther distance. Some things i would do differently in building a catapult next time would be to consider the launch angle. Having a launch angle of 45 degrees would give the maximum distance. Although are launch angle was more than that, we had all the necessary materials and tools needed to make the catapult so we didn't have to buy anything. I enjoyed building and launching my catapult but if we did this again i would make the angle 45 degrees, add more weight to it, and find out and test better mechanisms to make the object travel a farther distance.
