Oh, dude, when an object is in free fall, it's like totally falling under the influence of gravity alone. So, technically speaking, the only force acting on it is gravity, making it accelerate towards the ground at 9.8 meters per second squared. But hey, don't worry, it's not like the object is free-falling emotionally or anything like that, it's just physics doing its thing.
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.
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.
9.8
The only force that can act on an object in free fall is gravity.
true, liner regression is useful for modeling the position of an object in free fall

True. Got that right on a test :)
The object is said to be 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.
An object in free fall is one that has only the force of gravity acting upon it.
A falling object.
