Microgravity is a state in which the gravitational acceleration acting on a body or object is very low, approaching zero. This condition can occur when an object is far from any massive celestial body, or when an object is orbiting Earth or another planet and is experiencing free fall around it. In this state, objects appear weightless, and may appear to float freely. Microgravity has a significant impact on various physical and biological processes, including combustion, fluid behavior, and cell growth, making it an area of great interest for space exploration and research.
