The Science of Levitation (Orbit)

It is human nature to explore new thing and the new thing which I was going to explore was the question that when we jump why doesn't the earth below is moves forward. The answer was much simple than anyone would thought, it is because all of our surrounding revolves with the revolving earth even the atmosphere in which we jump. Newton's motion law explains it well that the frame of reference is same for us when we jump out stand on earth and everyone on earth will see us stationary but any outsider suppose an alien far away from Earth sees us moving forward in parabolic path. It could be demonstrated by throwing a ball up in moving car or train in motion and the ball will land in your hands always.

The next thing which is to be known after knowing the above answers is that how one move with the same speed as the earth moves without falling down and this led us to the study of setting up satellites in the orbit to understand it let us suppose we throw a ball from the top of a tall tower and till the ball had velocity whose resultant is greater than of gravity it will move forward and when is velocity decreases it will fall toward earth,so it is clear that speed plays a major role in setting up a satellite into orbit and instead of moving perfectly vertical we move horizontal to set up something into orbit let us find out why? To solve this problem we have to know that for every 8000 meters in earth towards horizon the earth bends 5 meter because the earth is a sphere and Newton was the first to know if a body moves down towards earth and if it's speed is faster than 8km per second it will never be able to touch the ground because at every 8km earth will bend by a radius of 5 meter so if we can maintain some height and velocity at the initial state to the satellite it will revolve the earth on its own as the speed will be provided by gravity itself. And if we are able to cross the speed barrier of 11.2km per second then we can escape earth's gravitational field if moved away from the planet. And we all know how much revolution has been brought by the satellites in our everyday life the list will go countless.
 Let's think how would you set up something into orbit if shape of Earth was square? All ideas and remark will be accepted in comments.
