No, in the sense that it is still attracted by Earth (otherwise it wouldn't be in orbit!). But for somebody within a space capsule for example, the gravity can't be felt. Such an object is said to be in "free fall".

What else can I help you with?
Imagine you are on a spaceship that is far from the sun or any planet Explain why 500 kg piece of equipment would be difficult to move even though the object mold be weightless?
Even though the object is weightless due to being far from any gravitational pull, it would still have inertia, requiring the same amount of force to move and stop it as it would on Earth. Without gravity, there is no friction or resistance to help with pushing or stopping the object, making it difficult to control its movements in a weightless environment. Additionally, any movements could cause the equipment to drift uncontrollably, making it challenging to reposition.
What is the weight of a falling object that has a mass of 16 kg?
0 because while the mass remains at 16 Kg, as the object is falling its weight (caused by the pull of gravity on its mass) becomes 0 as its acceleration equals that of the acceleration due to gravity. (This is why things seem weightless when in orbit round the Earth - they are actually falling).
Which object in the solar system is closest to Earth?
the object that is nearest to earth is moon
Is an object that is not moving relative to Earth a blue shift?
No, an object not moving relative to Earth is not a blue shifted object. With no relative motion, an object will not be subject to Doppler effect and will not red or blue shift. For an object to be blue shifted, the distance between the object and Earth must be decreasing. The object must be closing on Earth or vice versa.
Why do scientist use the unit mass instead of saying weight?
Mass doesn't change where ever the object or thing is but weight changes depending on where it is(depends on acceleration due to gravity-g) Eg: Mass of object doesn't change either it is on moon or earth but weight changes(on moon it is 1/6 of that on earth).
Why is an object considered weightless when there is no normal force or when an object is in freefall?
An object is considered weightless when there is no normal force acting on it because weight is the force exerted by gravity on an object's mass. In freefall, the object is only subject to the force of gravity, which causes it to accelerate with the same acceleration as the object itself, resulting in a sensation of weightlessness.
When are you considered to be weightless but still have the mass?
when your on the moon, or anywhere that has less gravity than earth.
What is the difference between a truly weightless object and a obect that is weightless because it is free fall?
A truly weightless object experiences no gravitational force, such as an object in deep space far from any massive body. An object that is weightless due to free fall is still under the influence of gravity but is in a state of free fall where the force of gravity and the acceleration of the object cancel out, making it feel weightless.
What is a situation in which an object is weightless?
An object is weightless when it is in free fall, such as when an astronaut is orbiting the Earth in the International Space Station. In this situation, the object is technically still affected by gravity but experiences a sensation of weightlessness because it is falling at the same rate as its surroundings.
How come an object can never be weightless?
gravity and mass...
Why an object becomes weightless in outer spaceaway from any planet or star?
Gravitational forces are much reduced by distance. Also, they would be fairly well balanced in all directions. However, there would probably still be some detectable gravitational force. The other definition of "weightless" is when an object is still in a gravitational field, but in "free fall". That's why astronauts orbiting Earth are "weightless".
Why isn't and object free fall really weightless?
rawr
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.
Why are astronauts floating above the Earth in a Space Shuttle really no weightless?
Weight is an expression of the gravitational force acting on an object. When the space shuttle is in orbit around the Earth, it is held there by the Earth's gravity. Since gravity is still acting on the shuttle and the astronauts inside, they still have weight. They are described as "weightless" because an object in orbit is in a constant state of free fall.
can a weightless body have inertia?
Yes, a weightless body can still have inertia. Inertia is the resistance of an object to changes in its motion, and it is determined by the mass of an object rather than its weight. Even if a body has no weight due to being weightless in space, it will still have inertia based on its mass.
Do objects in Earth's orbit appear to be weightless because they are in free fall?
Yes, exactly. A useful way to think of an object in orbit is that it is falling towards Earth much like anything else but, because of its velocity and distance from earth, it keeps missing the ground. This seems slightly contradictory -- a weightless object under the pull of gravity -- but it isn't, really. Suppose you're in an elevator that's had its cables cut. (Heaven, forefend!). Gravity accelerates you and the elevator Earthward at exactly the same rate, so you feel like you're floating relative to the elevator, but you and the elevator are just falling at the same rate.
How can an object in space warp space and time if it is essentially weightless and would not therefore create any gravitational influence on it?
Weightless is not the same as massless -- it is an object's mass that warps space (and time) around it, creating a gravitational field.
