Weightlessness.

what is it called when an orbiting astronaut floats and feels no gravity?
An orbiting spacecraft or space station continues in orbit because its forward momentum carries it around the planet even as gravity tries to pull it down. So astronauts are literally "falling" toward the Earth when they are in orbit. This "freefall" means that they do not experience the actual acceleration force. Nothing in an orbiting spacecraft experiences effective gravity, so moving around is much easier, and objects have to be secured to prevent them from floating away.However, objects still have the same mass, so will have the same inertia if moving: an iron weight thrown across the cabin will impact with the same force if it hits something, and a huge satellite in a shuttle launch bay will still require a lot of energy to push from the bay. But the absence of gravity would make exercises such as a one-hand push-up ridiculously easy to do.
How do astronaut's move on the moon compered with the earth?
There is less gravity on the moon than earth. Earth has a lot of gravity which is why things feel heavy and fall as quick as they do. The moon has way, way less gravity therefore it feels like you are weightless and drift a little.
Why do astronaut feel weightless in space?
They actually are weightless, due to the fact there is no gravity in space. However a sky-diver would say he/she feels weightless, but they are experiencing free-fall.
Why an astronaut in a space shuttle feels weightless?
"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).
How does it fell to be in space?
astronaunts feels like gravity is moving on and he feels free.
A freely floating Astronaut pushes another freely floating astronaut in an artificial satellite What is the force applied by the 1st astronaut on the 2nd one?
The force applied would be zero as a freely floating astronaut feels weightlessness as the gravitational force acting on him is zero.
How come astronauts can float around in space?
They are in free fall. That is, the ONLY force acting on them is gravity, and to them, that feels as if there were no gravity. Imagine the person next to a spacecraft - and both are orbiting Earth. The person accelerates towards Earth - but so does the spacecraft, and it does so at the same rate, so they stay close together, at least initially.
What is the gravitational force acting upon an astronaut when lifting off?
The actual gravitational force on the astronaut ... the force attracting him to themass of the earth ... is exactly the same as it always is, and is equal to his weight.But ... he feels as if there's more force on him, as if his weight has increased.That's because he's accelerating aboard the launch vehicle, and there's no wayto tell the difference between the force of gravity and the force of acceleration.
Is it possible for the body to have zero velocity and non zero average acceleration?
Yes, satellite orbiting the Earth in a Geo-Stationary Orbit has 0 Velocity relative to a point on the Earth, BUT it experience the 'Pull' (acceleration) of Gravity, which prevents it from escaping its Orbit. The Gravity is LESS than that at the surface of the Earth, but not 0. The feeling of WEIGHTLESSNESS is not due to Zero Gravity, but due to the fact that Object is FALLING through its Orbit. A Person Falling "feels" Zero Gravity.
What is training like to be an astronaut?
take your lower lip and pull it up over you fore head... that what it feels like
Why does an astronaut weigh less on the moon?
An astronaut weighs less on the moon because the moon has less mass than Earth, meaning weaker gravitational force. Weight is the result of the gravitational force acting on an object's mass, so with less force on the moon, the astronaut feels lighter.
Can a planet orbit a black hole and why?
Yes, a planet could orbit a black hole, just like it could orbit a star. Gravity would bind them together. A planet orbiting 93 million miles from the sun feels exactly the same as if it were orbiting 93 million miles away from a black hole with the same mass as the sun has.
