It's called micro gravity but basically yes. They are just falling around the planet.
Weight is an expression of the gravitational force acting on an object. When the space shuttle is in orbit around the Earth, it is held there by the Earth's gravity. Since gravity is still acting on the shuttle and the astronauts inside, they still have weight. They are described as "weightless" because an object in orbit is in a constant state of free fall.
Space shuttle astronauts in orbit do not hit their heads on the ceiling because they are in a state of free fall, experiencing microgravity. In this condition, both the astronauts and the shuttle are falling towards Earth at the same rate, creating the sensation of weightlessness. As a result, they float inside the shuttle and are not subject to the forces that would normally cause them to collide with surfaces.
This is known as free fall or microgravity. In this state, astronauts and objects inside the shuttle experience a sensation of weightlessness because they are falling at the same rate as the shuttle around the Earth, creating the illusion of being in a state of weightlessness.
they are not actually flying they r in continous free fall
As there is no gravity in space, everything will float........... Because They're in free fall ........
Astronauts inside a falling shuttle experience weightlessness because they are in a state of free fall alongside the shuttle. This means both the astronauts and the shuttle are falling together at the same rate, so there is no sensation of hitting the ceiling despite the lack of gravity.
When you jump/fall from an inthinkable height without parachute or any other safety devices. When a bird retracts its wings and fall striaght down it is consiered a free fall.
In a free fall environment, you do not have gravity to separate things for you, so a centrifuge is a workable alternative.
Astronauts should and do exercise in freefall
"Weight" happens when the attraction of gravity on a mass is resisted, we only FEEL the weight when we are resisting gravity. Weightlessness therefore happens when gravity is not resisted - when you are in "free-fall".In a space when you are in orbit round the Earth, you are effectively in "free-fall" and therefore as you are not resisting gravity you are weightless (but not massless).
Its mass is the same(ignoring spent fuel) but the weight is a result of the gravitational pull, which is different in space. Actually the space shuttle never gets far enough from the earth for it's weight to change. The reason it seems weightless is because it is in free-fall.
Astronauts in space experience microgravity, where they are in a state of continuous free fall around the Earth. This creates the sensation of weightlessness. They do not completely overcome gravity, but rather experience an environment where the effects of gravity are significantly reduced due to the spacecraft's orbital motion.
