Short definition:Microgravity, also known as micro-g environment, is when a person or object appear to be weightless but the g-forces are never exactly zero. A clear example of microgravity can be seen when astronauts or objects float in space.
Detailed definition: Microgravity, also known as micro-g environment, is a condition in which an object or a person appear to be weightless, though the g-forces are never exactly zero. "Micro" means “very small”, so microgravity refers to the phenomenon in which gravity appears to be very small. The effects of this condition can be seen when objects and astronauts float inside a spacecraft or outside, while on a spacewalk.
Microgravity has a variety of effects on the human body. Muscles and bones, for example, can become weaker without having to work as hard. Furthermore, many things appear to behave differently in microgravity. Fire burns in different ways. Flames are more round when the pull of gravity is absent. There is a better growth of crystals. Their shapes are more perfect without gravity.
Etymology:
“Micro” from ancient greek mikrós/“small” + “gravity” from Latin gravitās/“weight”
Sample sentences:
In micro-gravity conditions the cryogenic liquids are without a free surface existing in a slushy state between solid, liquid, and gas.
Experience ´with crystal growth in microgravity shows potential to yield much better results.
