Why do astronauts experience less gravitational force?
They don't. They have just as much gravitational force on them as you and me. The difference is the two initial frames of reference. You and I are being held down to planet. They are "falling" around the planet in an orbital free fall.
Do astronauts feel gravity on space?
An object is said to be in free fall when the only force acting on it is its weight. All objects in a vacuum fall at the same rate regardless of their masses. All bodies in orbit, including the International Space Station (ISS), are in free fall, but as long as they are going fast enough their momentum keeps them in orbit instead of falling down. Since the net force acting on the astronauts and cosmonauts in the ISS are exactly the same as those acting on the ISS itself, with respect to the ISS they experience a net force of zero, which means that they are experiencing weightlessness.
Why do astronauts float weightlessly in space?
There is (apparent) zero gravity. The absolute gravity in orbit is about 90% of what it is on the surface of the earth, but the effective gravity is zero, and for a good reason.The fact is that in orbit, you are actually falling, but your forward speed is such that the curvature of the planet is dropping at the same rate that you are falling.And the astronauts are falling at the exact same speed as their capsule. This is called freefall.
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 high must a spacecraft be before weightlessness is detectable?
Its not a questions of height or altitude. Its about things free falling. A space ship falling around the Earth (everything in the space ship is also falling at the same speed) the astronauts are falling too. If you put a scale on the floor and an astronaut stepped on it, there is no downward force so it looks like they are weightless. Picture yourself in an elevator at the top floor. You're standing on a scale. Gravity pulls you and the scale, but the elevator floor prevent you from falling. The scale will measure your weight. If the elevator suddenly fell, it, you and the scale would all be accelerating towards the basement at 9.8m/s/s. The scale would read ZERO, because there is no force acting on the scale.
Do astronauts in orbit around the earth experience the same gravitational force as they do on ground?
Yes, but they do not "feel" gravity, because they are falling - "free fall" in orbit around the Earth.
Can you fly while you are in a space shuttle in space?
You may have seen photos or videos of astronauts who appear to be floating through the air while in space. They aren't flying, nor are they really floating, they are falling. Any orbiting spacecraft (such as the space shuttle or international space station) is actually falling around the Earth in a circular pattern. They have achieved enough speed (over 17,000 mph) to continue moving around the Earth without the Earth's gravity pulling the spacecraft down. Astronauts aboard those spacecraft are moving inside the spacecraft and falling along with them at the same speed giving the appearance that they flying or floating inside.

Why dont astronauts hit there heads on the ceiling of the falling shuttle?
Because they are strapped into the seat with more than one belt. because of the terminal velocity
Why do you not feel weightless if flying in a large airplane at a high altitute but if you were in an orbiting spacecraft you would constantly feel weightless?
That's because an orbiting spacecraft is constantly falling, but ... let's hope ... the aircraft you're riding in is not.
Why do astronauts in orbit feel weightlessness?
they are falling through space around earth
Are astronaunts in orbit around earth really weightless?
The astronauts appear to be weightless as they are in a constant freefall, falling at the same speed as the space vehicle they are on. They are 'falling' but due to their angular speed, they are 'falling' around the earth, so don't crash into it. They still have their mass, but you can't really weigh the astronauts as any scales you try to use will read zero as the scales will also be 'falling' at the same rate.
Why do astronauts seen to fly inside their spacecraft?
They are in a state of weightlessness caused be the distance from earth. This is because of one of 2 reasons. If the space craft is in a orbit around the planet, the weightlessness is caused by a constant falling towards the planet, but always misses the ground (you can get the same effect if you are inside an airplane dropping towards earth with more the 9.82m/s). If the spacecraft have left the earth gravity alltogether, there are simply no force pulling the astronauts downwards, making them seem to float. Gravity is caused by the fact that materia bend the time/space field in a way that matter is drawn towards one another. You need a very big mass for this affect to be noticeable though, like for example, the mass of Earth on a person.

Does gravity affect astronauts?
Astronauts are in a continuous free fall the whole time they are in orbit. You may now ask though, why don't they hit the ground? They never hit the ground because they are traveling fast enough laterally that they miss the earth. In a sense, yes gravity does affect them, that's how they stay in orbit, but they do not feel the affects of it because they are always falling. If you were to sky dive or jump off of a high surface, you would experience the sensation of zero G, you just do not experience the no friction/ airless environment that they do. A quick factoid, when astronauts come home from shuttle missions, from being in the weightless environment for that amount of time, they actually loose some of their muscle mass, in some cases the loss is so great that some astronauts will not be able to walk away from the shuttle once it is back on earth. This is the main concern on future Mars Missions. Being out of earths influence of gravity for months on the trip to Mars can be fatal.

Are astronauts in space shuttle in free fall?
It's called micro gravity but basically yes. They are just falling around the planet.
