We ask ourselves which is easier to launch without return from Earth: an object vertically, reaching escape velocity, or the same object horizontally so that it goes into orbit.
After the analysis, a clear conclusion is reached.
The topic is from physics, in particular from gravitation where we use the conservation of mechanical energy and Newton's second law.
