free fall occurs when only gravity is acting on a object, and nothing else. if air is present, it provides air resistance, which immediately eliminates free fell

Why can a 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.
What kind of friction occurs during free fall?
air resistance is the most likely to occur
What only occurs when there is no air resistance?
-- "free fall" -- absence of terminal velocity
Will an object accelerate in free fall?
Free fall is the situation when the object's motion is influenced only by gravity.In that situation, the object continuously accelerates.Before we go getting into air resistance, terminal velocity, and all that stuff,it must be noted that falling through air is NOT free fall.
Why can free fall occur only where there is no air?
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.That's more or less the definition of a free fall - that no other forces are at work, except for gravity.

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

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 kind of friction occurs during free fall?
air resistance is the most likely to occur
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.

Is a satellite circling the Earth above the atmosphere in free fall?
Yes it is in free fall because gravity is the only force acting on it. (no air resistance)

When the only force acting on force a falling object is air resistance the object is said to be in free fall?
True (:
