Micro-gravity behaves as weightless for people or objects. When astronauts and objects float in space, the effects of Microgravity can be seen. In other ways, micro-gravity can also be experienced. Micro-gravity refers to the situation where gravity appears very small. “Micro-gravity” means “very small.” Astronauts will float in a micro-gravity on a spacewalk or outside. Easily shifting large objects. For… Read more →
