So, I am very new to construct, have 0 idea on what is going on in this program. I was given a program to fix a few stuff in, and one of those things was to fix the small ball going too fast around the bigger ball. I'm working on a physics program, where the small ball is the electron and the big one is the nucleus, right now there are 2 balls and 1 small one, and I tried to remove one of the balls but idk how to cuz everything seems to be in one group rather than seperated. So do I make a totally new one or can I save time and work on this one and how?
