What is the net force acting on a freely falling 1-kg ball if it encounters 2 N of air resistance?

The idea is to calculate the downward force of gravity, and then subtract the air resistance, since it acts in the opposite way. This assumes that the ball falls directly downward.

What is terminal motion?
the constant speed that a freely falling object eventually reaches when the resistance of the medium through which it is falling prevents further acceleration.
What is exactly meant by a freely of falling object?
If an object is in "free fall", it means that the only force acting on it is gravity.
What is the only force acting on a freely falling object?
Gravity is forcing an object to fall to the ground. Another force is friction from air pressure on the falling object.
How do you increase the time of descent of a freely falling body?
*by reducing the weight or density of the falling object. *By introducing resistance to the falling object in the form of flat light weighted object. *giving parachute.
What is the net force acting on a 25N freely falling object. What is the net force when the object encounters 15 N of air resistance. When it falls fast enough to encounter 25 N of air resistance?
You call it a "25N object". Where did it get that label ? It must be because when it's down on land, not freely falling, and you put it on a bathroom scale, the scale reads "25N". When you see that, you know that the mutual forces of gravity in both directions between the object and the Earth are both 25N, and for convenience, you begin to refer to that object as a "25N object". As long as the distance between the object and the center of the Earth remains pretty much the same, so does the gravitational force between them. With that knowledge, we can go on and answer your question. First, the "freely falling" bit. An object plowing through air is not freely falling, because it has to keep pushing air molecules out of its way. Since you call the object a "freely falling" one, we know that there is no air in its path, and there are no springs, weights, bungee cords, people, or rays of mysterious radiation exerting other forces on it. It's just freely falling, somewhere near the surface of the Earth. And since the only force on it is the force of gravity, the magnitude of the force is that old 25N again, acting in the direction that we call "down".

What is the meaning of Free Falling?
Let's imagine there is no air resistance and that gravity is the only thing affecting a falling object. Such an object would then be in free fall. Freely falling objects are affected only by gravity
Is there any force acting on an object which is falling freely?
Yes. The definition of "free fall" implies that gravity from Earth - or perhaps from different objects - is acting on the body.

A body falling freely from a hight towards the earth moves with uniform?
It moves with uniform acceleration,because it has a constant force acting on it (its weight).
Neglection air resistanceabnody falling freely near the earth surface?
Neglecting air resistance, a body falling freely near the earth's surface falls with an acceleration of 9.8 meters (32.2 feet) per second per second, regardless of how big, small, light, or heavy it is.
What opposing forces act on an object falling freely through the atmosphere?
The forces that affect the rate of a falling object are Gravity and Air Resistance. Gravity affects the speed and the velocity of the object by speeding it up as it falls closer to the earth, and Air resistance works against the object pushing against it.
The sumof the kinetic and potential energies of a freely falling body is?
If the body is freely falling, this sum will remain constant.
What is freefalling?
free falling is whena gravity is pulling a object or anything down and no other forces are acting on it.
