I don't quite understand why you mix "gravitation" and "weightless" in the question. The gravitational acceleration of Earth is 9.8 m/sec2 near the surface; further away, it will gradually decrease. The presence of air - if that is what you referring to - is quite irrelevant to the fact that there is gravitation.
What else can I help you with?
Are objects in a free-fall completely weightless?
Only from the object's frame of reference because the object's inertial motion is equal to the gravitational acceleration. Weight equals mass times gravitational acceleration (W=mg), so you would feel weightless, but your mass stays the same.
What is the numerical number for the gravitational acceleration?
The numerical value for the gravitational acceleration on the surface of Earth is approximately 9.81 m/s^2.
What is the gravitational acceleration of an object on the surface of the earth?
At or near the surface of the earth, the acceleration due to gravity is 32 feet per second per second
How does Acceleration relate to gravity?
Acceleration is the rate of change of velocity over time. In the context of gravity, objects near the Earth's surface experience a gravitational acceleration towards the center of the Earth of approximately 9.81 m/s^2. This gravitational acceleration causes objects to fall towards the Earth at an increasing rate due to the force of gravity acting upon them.
A hammer is dropped on Planet X. If the hammer has a mass of 3 kg and a weight of 9N what is the gravitational acceleration of Planet X Is it more or less than that of Earth?
The gravitational acceleration of Planet X can be calculated using the formula weight = mass x gravitational acceleration. In this case, on Planet X, gravitational acceleration is 3 m/s^2, which is less than Earth's gravitational acceleration of 9.8 m/s^2.
Does a body which orbits the earth became weightless?
A body in orbit is in free fall, so no weight would be experienced by it. It moves under gravity, but the gravitational force is exactly matched by its acceleration.
Why is the gravitational accleration of any object near Earth is the same?
The gravitational acceleration of an object near Earth is the same because it depends only on the mass of the Earth and the distance from the center of the Earth. This means that all objects experience the same gravitational acceleration, regardless of their mass or composition.

What is the rate of acceleration of earth's center?
Earth's gravitational acceleration is approximately 9.8 m/s^2, or 1g.
What is the gravitational acceleration of an object on the surface of the earth?
At or near the surface of the earth, the acceleration due to gravity is 32 feet per second per second
Magnitude of gravitational acceleration on mercury?
Mercury's acceleration of gravity in m/s^2 is 3.59
What balances the gravitational attraction of the earth on a falling object?
acceleration
How much you weigh at the center of the earth?
At the center of the Earth, you would be weightless because the gravitational forces from the Earth's mass would be pulling equally in all directions, effectively canceling out the force of gravity acting on you.
Gravitational force decreases with distance. What does this mean for a space traveler who leaves earth in a spaceship?
While his ship is accelerating away from the Earth he will feel heavier as acceleration acts a lot like gravity. Upon decelerating he will begin to feel lighter, a lot lighter, until he is almost weightless.
