A 20 N falling object encounters 4 N of air pressure what is the magnitude of the net force on the object?

The object experiences 20 newtons pulling it down due to gravity. But it also experiences 4 newtons air resistance pushing it up. 20 - 4= 16 newtons net downward force on the object.

Is it possible for a falling object to have a positive acceleration?
If you define the positive direction as pointing down, then the falling object has positive acceleration.Its magnitude is 9.8 m/s2.
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.
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.
The two forces acting on a falling object are gravity and what?
Air pressure.
What is change in the velocity of a falling object?
Any change in the velocity of anything is known as 'acceleration'. In the case of a falling object near the Earth's surface, the direction of the velocity is constant, and its magnitude increases by 9.8 meters (32.2 feet) per second, every second.

When a 25 n falling object encounters 15 n of air resistance the net force on it is.?
25-15= 10n

What is the net force that acts on a 10N falling object when it encounters 4N 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

Air pressure.
How do you find the magnitude of a free falling object?
force= mass (kg) x acceration(m/s2) meters per second sq.

Explain the effect that gravity has on the velocity of falling objects?
The force of gravity causes the falling object's velocity to grow in magnitude by 9.8 meters per second every second, while its direction remains constant.
Is mass the magnitude of the force due to gravity on an object?
No mass is not the magnitude of the force due to gravity on an object. Mass is the stuff of which the object is composed. The magnitude of the gravitational forces between the object and Earth ... or whatever planet the object happens to be on ... is the object's "weight".
Objects falling through the air experience a type of friction called .?
Air Resistance or Drag is the type of friction that a falling object encounters while in the air. It has three classifications which are the lift-induced, the parasitic drag and last the wave drag.
Is the vertical motion of a falling object dependent on the mass of the object?
Gravity's action on a falling body is dependent on the masses of both bodies and the difference between their centers. Typically the falling body's mass is negligible, being on orders of magnitude smaller than the larger body, and will not affect the acceleration to any measurable degree. So, typically the answer would be: No.
