If you just did the simplest gravity sim then things will all fall in unison:
Try be better at asking questions: You have to understand that others can’t see inside your mind.
e.g. Explain your current setup, show screenshots/videos, upload a blend file, etc.
Stick to one question per-thread - make sure you ask the right question first time. Endless “Thanks for that but one more thing…” threads are annoying. Forcing others to be dragging details out is annoying. Over time, users who do that will get fewer people willing to help them.
Good luck.
