What does the term zero gravity mean?

Zero gravity is a condition where you do not feel the force of gravity acting on your body. It is sometimes called weightlessness. This does not mean gravity is completely gone. Instead, it means that you and everything around you are falling together, so you do not feel your normal weight. This often happens in space or during free fall on Earth. The correct scientific term is "weightlessness" and sometimes "microgravity," because a small amount of gravity is still present everywhere.​
