An astronaut is floating feet down in a space shuttle which is orbiting at a height of R from the center of the earth What is the acceleration due to gravity g at her feet?

Three, the number of counting is three (3) , none other since no gravity is the norm without intervention inside the craft, Thus the Pythonian 3 shall be the default

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.
Has an astronaut ever floated off into space and is now lost?
Even though Hollywood depicts astronauts floating off in outer space in the movie "Gravity", it has never happened.
What anastronaut working in Space near the International space station says she feel weightless. What does she mean Does the astronaut no have weight?
It actually means that the astronaut is in free fall, and doesn't FEEL gravity. Gravity does affect the astronaut, so the astronaut will still be accelerated towards Earth. However, the astronaut won't feel the gravity.
If an astronaut weighs 125 pounds on earth than how much does it weigh on the moon?
Yes. Mass and weight are different quantities. The mass of the astronaut is always the same everywhere. The weight of the astronaut is the force on it due to gravity, which depends on the mass and the strength of gravity at the point on the planet, moon or space station the astronaut is standing on. The strength of gravity is known as "local acceleration due to gravity", and it is represented by the letter g. On the surface of the earth g is about 9.8 ms-2. On the surface of the moon g is about 1.6 ms-2 (a 6th that of the earth). On a space station, because the mass of the station is so small, g is effectively 0 ms-2. So, the weight of an object is the force on it due to gravity. The formula for weight is: W = mg Where: W = Weight (in Newtons) m = mass (of the object, in Kg) g = local acceleration due to gravity (in ms-2). Hopefully you see this formula is a restatement of F = ma. Your average man has a mass of about 70 kg. If you plug in the numbers you find the weight on the earth is 686 N, on the moon is 112 N, and on the space station it is 0 N (i.e. the astronaut is totally weightless).
What force acts on an astronaut standing still on the moon?
Gravity, mainly that of the moon. Gravity on the Moon is a lot less than on Earth but it works in the same way.
what is it called when an orbiting astronaut and feels no gravity?
Weightlessness.
Is floating affected by acceleration due to gravity?
no.
An astronaut inside a small space ship orbiting around the earth cannot detect gravity.If the space station orbiting around the earth has a large size can he hope to detect gravity?
If the size of the space station is large enough, then the astronaut will detect the change in Earth's gravity (g).
Does your weight change if the acceleration due to gravity changes?
If you're standing on something - yes. But if you're floating or falling, no.
What force keeps a moon from orbiting a planet?
The Moon is orbiting a planet; It is orbiting the Earth. The velocity /acceleration of the Moon and the gravitational pull between Earth and Moon are in balance, so the Moon remains orbiting the Earth. Similarly the Earth and Moon , as a binary system, orbit the Sun , and the acceleration and gravitational forces are in balance. So none of us collide.
What are all objects in space constantly doing?
Objects in space are always Floating and/or orbiting a larger object because of the lack of gravity in space.

What is the force that keeps planets orbiting star and satellites orbiting planets?
The force is called gravity. It is a force that works both ways, i.e. when the Sun's gravity operates on a planet, there isan equal an opposite force acting the other way but the Sun is so massive it hardly moves, because force equals mass times acceleration, so if mass is large the acceleration is low.
What can gravity cause?
* falling down * pouring down * rolling down * sliding down * raining down * snowing down * orbiting around * convection current * air pressure * water pressure * floating in air * floating in water
How does Acceleration relate to gravity?
Not at all. However Gravity can impart an acceleration - Gravitational acceleration.
How acceleration effect gravity?
Acceleration does not effect gravity. It is rather the other way round. Gravity can affect the rate of acceleration.
How does speed and acceleration effect gravity?
Speed or acceleration have no effect on gravity.
