This might be silly question for some people, yet better to ask than don't know the answer :(.
so the thing is , i know that centripetal force holds a thing to keep running on a path,
but when i think of Earth and all those planet which surround it, the centripetal force is gravity right ? and why those planets don't collide with Earth ?
Thanks
