That's more or less the definition of a free fall - that no other forces are at work, except for gravity. However, you can get a good approximation even with air, if the object is massive enough and doesn't fall for too long.

What else can I help you with?
How can free fall occur only where there is no air?
Free fall can occur in a vacuum or low air density environment because air resistance is not present to oppose the motion of an object. In the absence of air, the only force acting on the object is gravity, causing it to accelerate towards the Earth at a constant rate. This results in a true free fall where the object experiences no other external forces.
What only occurs when there is no air resistance?
In the absence of air resistance, an object in free fall will continue to accelerate at a constant rate (9.8 m/s^2), as there is no force acting to oppose its motion. This phenomenon is known as "free fall acceleration".
Why can a free fall occur when there is only no air?
free fall occur if there is no air because there is nothing to resist the fall of the object
When the only force acting on a falling object is air resistance the object is said to be in free fall true or false?
False. When the only force acting on a falling object is air resistance, it is not considered to be in free fall. Free fall occurs when an object falls solely under the influence of gravity with no other forces acting upon it.
Why can freefall occur only when there is no air?
An object is in free fall only if gravity is pulling it down and no other forces are acting on it. Because air resistance is a force, free fall can occur only where there is no air.
When an object in free fall?
An object is in free fall when only gravity and air resistance (drag) are acting on it. In space, free fall excludes drag.
What is the definition of free-falling parchute?
"Free fall" means that an object falls only under the influence of gravity; specifically, air resistance can be ignored. An open parachute does not normally fall in this category."Free fall" means that an object falls only under the influence of gravity; specifically, air resistance can be ignored.

Why can a freefall occur only when there is no air?
Freefall can occur in the absence of air resistance because the only force acting on the object is gravity. In the absence of air, there is no air resistance to counteract the gravitational force, allowing the object to fall freely.
Is this statement true or false when the only force acting on a falling object is air resistance the object is said to be in free fall?
No, that is false. "Free fall" means that the only force acting on an object is GRAVITY. Specifically, there may be no significant amount of air resistance. It's not quite possible for the only force acting on an object to be air resistance, since you can't really eliminate the effect of gravity. Though, if the object has the same density than the liquid or gas in which it is placed, the gravity may be cancelled for practical purposes.
Does free fall occur only when air resistance does not affect the motion of a falling object?
Yes, unless speaking about parachutists who refer to free fall as falling through the air without opening their parachutes.
What conditions are needed for free fall?
Free fall occurs when an object is only subject to the force of gravity, with no other forces acting on it. This means that the object is falling through a vacuum or in a situation where air resistance can be neglected. Additionally, the object must not be supported by any external means and must be in a state of unimpeded motion.
Is gravity in the only force acting on an object the object is in a what?
When an object is in free fall, gravity is the only force acting on it. This occurs when the object is falling under the influence of gravity alone, with no other forces like air resistance or drag affecting its motion.
