In the presence of a gravitational field, objects in free fall are uniformly accelerated. In a vacuum, all objects will fall at the same rate under the same gravitational attraction and would reach the ground at the same time. Falling through a fluid, resistance between the object and the fluid will cause the object to reach a maximum velocity as a parachutist does, being accelerated by the Earth's gravitation but being resisted by the air. All objects, having mass, have a gravitational field.
What else can I help you with?
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.
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.
What is the numerical value in meters per second of the acceleration of an object experiencing true free fall?
9.8
An object falling under the influence of gravity and no other force is said to be in free fall.?
true
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.
True or false a linear regression is useful for modeling the position of an object in free fall?
true, liner regression is useful for modeling the position of an object in free fall
When the only force acting on falling object is air resistance the object is said to be in free fall True or false?
true
When the only force acting on a falling object is air resistance the object is said to be in free fall. true or false?
true

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.
When the only force acting on force a falling object is air resistance the object is said to be in free fall?
True (:
An object is falling the influence of gravity and no other force is said to be in free fall?
true
True or false an object in free fall accelerates until it reaches terminal velocity?
True. Got that right on a test :)

What is the numerical value in meters per second squaredof the acceleration of an object experiencing true free fall?
The numerical value in meters per second squared of the acceleration of an object experiencing true free fall is approximately 9.81 m/s^2. This value represents the acceleration due to gravity acting on the object as it falls under the influence of gravity alone.
