Today we learned about forces and motion to help us with our arcade games. Our mentor used some of the launchers that Stephan, Day and Angie made as examples to show different ideas on how to launch the balls and stuff. She picked Stephen’s which I think is great because I thought it was the best, and it was made by a kid. She helped us to see that different balls that are different sizes need different force to get it to launch right. Like the heavier ones need us to pull the rubber band back a lot to even get it off of the board. That was more force. It is cool that learning about forces actually helped us with our designs.
