What is the net force acting on a 12 N falling object when it encounters 12 N of air resistance?

The net force would be zero, which means the falling object would no longer be accelerating, and would be falling at terminal velocity, which is a constant velocity. Weight is a downward (negative) force and air resistance is an upward (positive) force.
Fnet = weight + air resistance = -12N + 12N = 0N

What are the forces acting on a falling object on earth?
Gravity and air resistance.
What forces act on a falling object?
The forces acting on a falling body are gravity and air resistance.
What is the net force when the object encounters 15-N of air resistance?
It depends on the positive force acting on the object.
Which encounters the greater force of air resistance a falling elephant or a falling feather?
A falling elephant encounters a greater force of air resistance than a falling feather does. The force of air resistance can't be greater than the weight of the falling object. When the force of air resistance is equal to the weight of the falling object, the object stops accelerating, its falling speed becomes constant, and the force of air resistance doesn't get any bigger. So the force of air resistance against a falling feather can't be greater than the weight of the feather. But the force of air resistance against a falling elephant can be, and undoubtedly is, greater than the weight of a feather.
What are the forces acting on an object falling through the air?
Air resistance and gravity.
The only force acting on an object in free fall is?
gravity and air resistance both act on a free falling object.
What is air resistance and how does it affect a falling object?
Air resistance is the force acting on an object moving in air that tends to slow it down or produce drag. If a stone is falling, air resistance will be acting on it to try to slow it. Should we consider a jet moving through air, air resistance will be providing drag to slow the jet down.
When an object falls through the air encounters air resistance its overall speed will be than if it had not encountered air resistance?
The resistance do obstruct the object. The object always travel slower with air resistance. Air resistance is higher with velocity and the object falling through air would have a limited velocity that it can't go through.
When the only force acting on a falling object is gravity the object is said to be in what?
Gravitational Force.When the only force acting on a falling object is gravity the object is said to be in free fall. Free falling objects do not experience air resistance, or the drag force. Free falling objects on Earth accelerate downwards at 9.8 m / s^2.
What is the net force that acts on a 10-N falling object when it encounters 4-N of air resistance?
The net force is the difference between the 10N falling object and the 4N of air resistance So you solve 10N-4N is 6N
What are the forces acting on a falling object?
Gravity and drag (air resistance), if any.Where there is resistance, the mass and leading surface area of the object will define its maximum falling speed, which is called terminal velocity. At that speed, the drag force (air resistance) is equal to the accelerating force of gravity.
How does air resistance affect the acceleration of a falling object-How does air resistance affect the acceleration of a falling object?
It reduces the acceleration of the falling object due to friction.
When the only force acting on a falling object is air resistance the object is said to be a free fall?
No. Free fall is when nothing opposes the force of gravity.
When the only force acting on a falling object is air resistance?
The word "falling" implies there is a gravitational force also. As the object gains speed, the air resistance ("drag") increases, until it equals the gravitational force. After that there is no net (resultant) force, so the object goes at constant speed.
Will an object falling to the moon experience air resistance?
There is no atmosphere on the moon and any falling object should not experience air resistance.
How are gravity and air resistance related to the terminal velocity of a falling object?
Gravity and air resistance (drag) are the two opposing forces acting on the falling body. Gravity causes the object to accelerate (fall faster) while the air resistance causes the object to decelerate (fall slower). At a certain velocity called the terminal velocity these two forces are in balance and there is no change in falling speed.
How does air resistance affect the acceleration of a falling object?
As a falling object accelerates through air, its speed increases and air resistance increases. While gravity pulls the object down, we find that air resistance is trying to limit the object's speed. Air resistance reduces the acceleration of a falling object. It would accelerate faster if it was falling in a vacuum.
What is the name of the speed when air resistant and gravity stop a falling object from speeding up or slowing down?
Terminal Velocity is the speed that a falling object achieves when the drag forces that occur from air resistance are equal to the gravitational forces acting on the object.
When an object is falling at terminal velocity what is the net force acting on the object?
Zero. "Terminal velocity" means that the object is no longer accelerating; the downward force of gravity and the upward force of resistance are in balance.
What do balanced forces acting on an object really cause the object to do?
If an object is falling, and the gravitational force is the same as the air resistance acting against the object it is called terminal speed, the object does not speed up, nor slow down A balanced group of forces has the same effect on an object as no force at all.
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.
How does gravity effect a falling object?
If there is no air resistance, gravity will accelerate the falling object, that is, it will change its velocity.
What is the effect of air resistance on a falling object?
Air resistance creates drag and slows the object down
How does air resistance affect the acceleration of a falling abject?
Air resistance creates friction and slows a falling object.
