This is what happens when I try and make a pendulum. PLEASE HELP!!! THIS PENDULUM BREAKS PHYSICS!! By the way I'm not trying to make a constant one with a constant speed, I'm trying to make something that get slower over time. if you see this and don't know, just comment that you don't know.
Tell me in the comments what I did wrong, and then I'll make a project to see what each of them look like.
