# [Physics] Why do you experience low-gravity outside the Earth (but near it), and experience more gravity on it

Spacecraft, satellites, etc. They also experience zero gravity, weightlessness, or "micro gravity" when outside Earth, about 20-300+ miles beyond the escape velocity zone("atmosphere"). However, you experience full gravity on the Earth. Why does gravity decrease just slightly farther away?

Partly because the magnitude of the gravitational force decreases as $\frac{1}{r^2}$, so as the distance from the center of the earth, $r$, increases, the magnitude decreases. The bigger reason for spacecraft is because they are constantly in free fall, and there is no way to feel gravity when you are falling freely. The spacecraft are falling and moving forward at great enough speed that they literally fall "around" the earth. When you are in orbit, what prevents you from flying off in a straight line is the centripetal force supplied by gravity. So it isn't that there is no gravity, but that there is nothing pushing back up on you to give you the feeling of being heavy.
