Any object is weightless.
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.
The only force acting on an object in freefall is gravity. This force causes the object to accelerate downward towards the Earth.
Freefall is when an object falls under the influence of gravity alone, without any other forces acting on it. In a non-freefall scenario, objects may experience other forces such as air resistance or propulsion that affect their motion.
Freefall refers to the motion of an object falling solely under the influence of gravity, with no other forces acting on it except air resistance. During freefall, the only force acting on the object is its weight, causing it to accelerate downwards at a constant rate of 9.81 m/s^2 (due to gravity).
The apparent weight of an object is zero when it is in free fall or weightless due to being in orbit. In these cases, the object experiences no normal contact force from a supporting surface, so it does not feel any weight.
They do not. When an object such as the space is in orbit it is essentially in freefall. If you have been n a roller coaster you'll have found that you feel weightless when you are in freefall. The same effect applies on the space shuttle.

It depends on the shape of the object and therefore its drag coefficient. For example, you can slow down your freefall by spreading your limbs out.
Freefall is when an object falls under the influence of gravity alone, without any other forces acting on it. In a non-freefall scenario, objects may experience other forces such as air resistance or propulsion that affect their motion.
