Nobody likes concept builders!
Hello there, this extension was designed specifically to solve something called a concept builder. A concept builder is a type of exercise we do in our freshman physics class at DHS. Other schools might also be doing concept builders but I don't know if they do or don't. Only use this if you want to piss your teacher off and possibly fail a test. I just made this because I was curious and had some free time. All the responsibility is on you :)
