I'm currently calculus and scientifically illiterate, so please bare with my ignorance of the subject matter in trying to explain my question on how an orbit works.
The way I perceive it is as follows: You basically need to get an object moving "parallel" to the surface of the Earth so fast that it can't fall to the ground, and yet slow enough so it doesn't leave the Earth entirely, due to the fact that the surface is circular. The "parallel" velocity is fine tuned to a sweet spot where the object's distance never changes from the ground (assuming a circular orbit). And, since the object is in a vacuum, no further energy is necessary to power it since it's in a frictionless environment.
Would such ramblings be a correct interpretation?
Thanks in advance.
