the net force on bodies in stable orbit is nil, the force of gravitational attraction , is balanced by the centripetal force of velocity in a circle.
.
example, any orbit radius ( if orbit time not important)
choose your orbit radius, calculate force of gravity, tailor velocity to produce balancing centripital force
.
f=((G*m1*m2)/d^2) force of gravity
f = m2 *( v^2/d ) centripetal force
G = newtons constant
m1 = earth mass
m2 = satellite mass
d = orbital distance
for the circular motion of a satellite a centripetal force is requid. these force is supplied by the gravitional force between the earth and satellite this is trueall objects in the satellite is zero ie, the object in a satellite feel weightlessness
Weightlessness in space refers to a condition where objects and individuals experience a sensation of being weightless due to the absence of gravitational forces. This occurs when objects are in freefall towards a massive body, like Earth, allowing them to float freely inside a spacecraft. Despite the feeling of weightlessness, the force of gravity is still present, but all objects fall at the same rate due to being in orbit.
Astronauts inside the International Space Station experience a sensation of weightlessness due to the constant free-fall around Earth. This is because the spacecraft and everything inside it are in a state of continuous motion, falling towards Earth while also moving forward at a high speed, creating a feeling of weightlessness.
As the space shuttle orbits the Earth, both the shuttle and the astronauts inside experience the same gravitational acceleration towards the Earth. This gives the sensation of weightlessness because everything inside the shuttle is falling towards Earth at the same rate, creating the feeling of floating.
Because space doesn't have an atmosphere. I disagree, it is due to the fact that most of Space is a vacuum and gravity only works between masses ad a vacuum is not a mass so depending on how far you are from mass, there is either very little gravity or none.

Zero g forces give the feeling of weightlessness. It is not a certain speed that gives the feeling of weightlessness, but the change in the amount of gravity.
Experiencing weightlessness means feeling like there is no gravitational force acting on your body, causing you to float or feel light as if you are in space.
When you enter space, you encounter a feeling called weightlessness.
The feeling is called "falling".It happens because of the apparent lack of gravity,which leads to weightlessness.
At the top of a pendulum ride, people have the momentary feeling of weightlessness.
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.
Weightlessness occurs in space. Astronauts circling the earth in space experience the feeling of weightlessness.
A person in an artificial satellite around Earth would experience weightlessness due to the constant freefall towards Earth. They would also see the Earth rotating beneath them, experiencing multiple sunrises and sunsets in a single day. Additionally, they would be shielded from Earth's atmosphere and be able to see the curvature of the planet.
Vertical acceleration is linked to the sensation of weightlessness because when an object is accelerating upwards at the same rate as gravity, it creates a feeling of weightlessness. This is because the object and the person inside it are falling at the same rate, cancelling out the effects of gravity and making it feel like there is no weight.
Astronauts in orbit experience weightlessness because they are in a state of continuous free fall towards the Earth. This creates the sensation of floating in space, as there is no force pushing against them to create the feeling of weight.
The feeling of weightlessness is similar to the feeling you have when floating in a swimming pool. Buoyancy is a pretty good simulation of weightlessness. Although there is NO friction in space so you would be either dead from explosive decompression or (if you were wearing a space-suit) you would bee throwing up in your helmet from rapid spinning.
