Trebuchet

Week 4 trebuchet

This week we have been learning about this catapult called a trebuchet, it fires a tennisball. I have noticed that it is gravity-powered. The only thing that is not gravity-powered is the nail you pull out. I wonder if in the future that everything is gravity powered and you don't have to do anything not even have to put weights in it.
My data gathering is multi structural because I can use my materials around me to gather data but I can not always be right. My inferences are multi structural to because I like to wonder about things but sometimes they are not possible.
