So, recently for physics we were assigned a project of constructing a catapult to help us better understand the concept of projectile motion. This project taught me a lot. On the day of the launch, we got a certain distance that the softball we shot went, we had a certain initial velocity and final velocity and also a certain time it took to go x distance. The acceleration was constant. This helped us relate to what we were learning in class about projectile motion because it was a first hand experience of it.
