Our topic question is "How the angle of the Catapult affects the distance and height of the projectile"
After seeing several other similiar kinds of topics on the internet, the topic seemed relatively easy and fun for our team.
Modern Usage of Catapults
Aircraft Catapults: Used to launch planes when the runway is too short
Clay Shooting: Small catapults, used to launch clay targets
The basics of our Catapult would most likely be rubber band powered as using weights would be harder on a small model. It would be made of wood and plastic with a ping pong ball as the projectile.
Basic Concept of how the angle works
Normally the angle would be 45 Degrees as it gives you equal balance between both Distance and Height of the projectile, though when the angle is lower than 45, the distance might be further though you suffer in height, while if the angle is higher than 45, you would gain more height but lesser distance.
