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
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.
Even though Hollywood depicts astronauts floating off in outer space in the movie "Gravity", it has never happened.
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.
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).
Gravity, mainly that of the moon. Gravity on the Moon is a lot less than on Earth but it works in the same way.
Weightlessness.
no.
If the size of the space station is large enough, then the astronaut will detect the change in Earth's gravity (g).
Your weight is determined by the force of gravity acting on you, so it will change if the acceleration due to gravity changes. If the acceleration due to gravity increases, your weight will increase, and if it decreases, your weight will decrease.
On Ganymede, which is a moon of Jupiter, the acceleration due to gravity is about 1.428 m/s^2. To find the weight of the astronaut's spacesuit on Ganymede, you would multiply the mass of the astronaut by the acceleration due to gravity on Ganymede. Therefore, the weight of the astronaut's 900kg spacesuit on Ganymede would be about 1286 N.
Gravity is proportional to the mass and inversely proportional to the square of the distance of the centre of the body or bodies.As the shuttle orbits at a comparatively low altitude and the mass remains constant the force diminishes only slightly. Being in free-fall does not mean there is no gravity.
Objects in space are always Floating and/or orbiting a larger object because of the lack of gravity in space.
Gravity can be simulated in an orbiting spaceship through methods like rotation, producing centrifugal force that mimics the effects of gravity. This can create a feeling of weight and stability for astronauts on board. Additionally, there are artificial gravity systems that use acceleration or magnetism to replicate gravitational forces in space.

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.

Acceleration does not effect gravity. It is rather the other way round. Gravity can affect the rate of acceleration.
