Why Isn't "Zero G" the Same as "Zero Gravity"?
This Quick Question explains the difference between gravity and g-force, and how you can experience zero-g in space even when it's not zero gravity!
==========
Zero G, a phrase that people use all the time to describe the phenomenon of perceived weightlessness. Usually in space. But zero G does not mean zero gravity because there's gravity everywhere. If there were truly no gravity in space, planets and stars wouldn't even form, let alone orbit around each other. So gravity is a thing, everywhere all over. But we sometimes refer to the effects of gravity in a specific way as G-force. Despite its name, not only is it not a measurement of gravity, it's not a measurement of force either. It's a unit of acceleration, and that acceleration is usually caused by gravity. Officially, one G is the acceleration of an object caused by gravity near the surface of the Earth. So you know, you throw your phone out your window, you jump up into the air or d...
