I am new to this forum so do not know all the rules of posting. So please don't mind if I have missed something. I have not been doing any physics and stuff for many many years, but have been having lots of curiosity about stuff, so will dare to ask it here. I understand that orbits are due to gravity. I have read ton of articles on this but it still does not make sense to me. So in my example I will exclue moon an sun so to get a better idea. If I throw a ball in the space, it will come back to earth. If I throw a ball at much fast speed, it will come down but will have a little curve. If I throw it fast enough, it will form an orbit around earth. Bases on my 3 statements above, following are my questions: 1) Are all my statements above true? 2) How fast I need to throw the ball so that it forms an orbit around earth? 3) How far will be the orbit from earth and why? 4) What will be the shape of the orbit? will it be perfect circle or ellipical? 5) How fast I have to throw so that it just blows away in the space, free of gravity of earth? I know the above questions are pretty basic, but I am really trying hard to understand and reading so much articles are just confusing me more and more. Thanks in Advance.
