One of the beauties of physics is that there are usually different ways to view and explain a given phenomenon. Is the following explanation valid? “Satellites remain in orbit instead of falling to Earth because they are beyond the main pull of Earth’s gravity.”

No, no, a thousand times no! If any moving object were beyond the pull of gravity, it would move in a straight line and would not curve around Earth. Satellites remain in orbit because they are being pulled by gravity, not because they are beyond it. For the altitudes of most Earth satellites, Earth’s gravitational field is only a few percent weaker than it is at Earth’s surface.
