I was reading in a book about the basic concept of launching satellites into orbit. I came across a paragraph saying,
If we take a body high above the surface of the earth, and then project it with some horizontal velocity, it will describe a parabolic path and fall back onto the Earth's surface. If the magnitude of the velocity is increased, the horizontal range also increases. We keep on increasing the horizontal velocity of projection, till at certain point, a stage will come when the body will not hit the earth, but will always be in a state of free fall under gravity in an attempt to fall to the earth.
I did not exactly understand the last statement .What do they mean by always be in a state of free fall ?
This may seem basic but I'm having trouble visualising it. If someone would explain what is the meaning of the last statement, that would help me a lot.
EDIT: After reading the answers, I have one last doubt. How would we analyse the motion of the satellite then ? Would it be rectilinear motion, like any other free falling body, or circular motion around the earth, as we generally think of a satellite, or both( I don't understand how that would work). Or does it completely depend on the frame of reference? Thanks for your time.
