AST 101 Lecture 7 Newton`s Laws and the Nature of Matter
... There is no mysterious force which keeps bodies in orbit. Bodies in orbit are continuously falling. What keeps them in orbit is their sideways velocity. The force of gravity changes the direction of the motion by enough to keep the body going around in a circular orbit. An astronaut in orbit is weig ...
