Detailed explanation-1: -Microgravity is the condition in which people or objects appear to be weightless . The effects of microgravity can be seen when astronauts and objects float in space. Microgravity can be experienced in other ways, as well.
Detailed explanation-2: -Because they’re all falling at the same rate, objects inside of the station appear to float in a state we call “zero gravity” (0g), or more accurately microgravity (1x10-6 g.) The condition of microgravity comes about whenever an object is in free fall.
Detailed explanation-3: -Weightlessness is a condition when your body is in free fall and the acceleration is downward at gravity. This condition can be defined by the term zero gravity. So weightlessness occurs when there is zero support of force on our body.
Detailed explanation-4: -In space, astronauts and their spaceship still have mass and are still acted upon by Earth’s gravity. In this sense, they still have weight, even though Earth’s gravitational force is smaller in orbit than it is on Earth’s surface (Box 1). However, they do not feel their weight because nothing is pushing back on them.
