: Hello! I have to answer a few of the questions that Issac Newton asked (supposedly, at the begining of his career). I cannot find any real information on them and I am completely inept when it comes to science. Please help if you can!! Thanks!
: Here they are:
: Why do the planets move as they do?
: What keeps them from hitting each other? Nothing keeps the planets from hitting each other!!
: What keeps them from falling down? A body in motion wants to stay in motion. The planets want to keep going in a straight line, but gravity keeps pulling them back to the bigger planet, so it looks like they are going in circles-- which they are..
: How can people walk on a spinning earth? Gravity!
: Thanks!
