If we travel 100 km vertically from the surface of the earth, will we no longer be pulled by earths gravity and float into space? Same question as above yet with 1000 km. How far up vertically do we have to go to escape earths pull and how wide/long is the earths gravitational influence. Does an object stop being affected by earths gravity after it crosses the karman line if its mass is to small. Im sorry for so much questions but if you could answer them all id be eternally grateful.
