How does Matter Behave in Zero Gravity?
Zero gravity is often used as a reference to weightlessness, circumstances where objects lose apparent weight and begin floating. This generally occurs in orbit or anywhere in space not close to a celestial body, i.e., astronauts traveling between the Earth and the Moon. Although in orbit the Earth’s gravity still exerts pull, because objects in orbit are in a state of continuous free-fall, this gravity does not press astronauts against the floor. Although objects in orbit are not really experiencing zero gravity, the term as a synonym for weightless has stuck, and will be used throughout the rest of this article. In zero gravity, everything not tied or bolted down floats. An object at rest stays at rest, but an object in motion continues to move until it hits a wall or another object. Released liquids, such as orange juice, form into bubbles due to surface tension and float around until sucked up. Bubbles can merge together to create larger bubbles. Zero gravity is not a good place to
