Air resistance acts in the opposite direction of an object's motion to reduce its speed. The force of air resistance or drag is given by the following formula:
FD = 1/2 A CD ρ v2
where
A is the projected area of the object
CD is the drag coefficient
ρ is the air density
v2 is the relative velocity of the air

Do the velocity of falling objects does not change?
If there is no air resistance, they will fall faster and faster.If there is air resistance, they will eventually approach a "terminal velocity", a maximum speed, at which the downward pull of Earth is counteracted by the backward pull of air resistance.If there is no air resistance, they will fall faster and faster.If there is air resistance, they will eventually approach a "terminal velocity", a maximum speed, at which the downward pull of Earth is counteracted by the backward pull of air resistance.If there is no air resistance, they will fall faster and faster.If there is air resistance, they will eventually approach a "terminal velocity", a maximum speed, at which the downward pull of Earth is counteracted by the backward pull of air resistance.If there is no air resistance, they will fall faster and faster.If there is air resistance, they will eventually approach a "terminal velocity", a maximum speed, at which the downward pull of Earth is counteracted by the backward pull of air resistance.
How does air resistance change the longer an object falls?
The force the air resistance do against the object is proportional to it speed (F=C*v^2, usually, where C is a constant and v is the speed). So, the higher the speed, the higher the force. If an object is falling, the gravity is probably responsible for it. When the force of the gravity is equivalent to the force made by the air resistance, the speed of the object remains constant. To answer your question directly: without air resistance, the graphic position X time would be parabolic. With air resistance, it looks like an decaying exponential.
Why parachutists do not fall with constant accelerating motion?
Due to air resistance as the resistance is directly proportional to the speed but at certain speed called transitional speed or critical speed the resistance become directly proportional to square the speed so the resistance increase decreasing the falling speed.
The speed when falling objects no longer accelerates due to air resistance is?
The speed when falling objects no longer accelerates due to air resistance is the maximum falling velocity.
What features of an object will affect air resistance?
the amount of air resistance on an object depends on the size, shape, and speed of the object. Air resistance is the force that opposes the motion of objects through air.

How does the force of air resistance depends on an object's speed?
In general the resistance increases by the 4th power of the speed.

How does air resistance affect the acceleration of falling objects?
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.
How does water or air resistance against an object increase speed?
It doesn't increase speed. The word resistance means to resist. In other words it decreases speed.
how do objects fall when there is no air resistance?
In the absence of air resistance (friction) objects will fall at the same speed. Hope this still helps :)
What is the effect of increasing speed on air resistance?
it gets faster.
How train speed is affected by air resistance?
Air resistance makes it difficult for the train to go beyond a certain speed, since the engine can no longer keep up with the amount of energy lost due to air resistance.Air resistance makes it difficult for the train to go beyond a certain speed, since the engine can no longer keep up with the amount of energy lost due to air resistance.Air resistance makes it difficult for the train to go beyond a certain speed, since the engine can no longer keep up with the amount of energy lost due to air resistance.Air resistance makes it difficult for the train to go beyond a certain speed, since the engine can no longer keep up with the amount of energy lost due to air resistance.
How would adding air resistance change the results?
air resistance will increase the time for an object to fall to the ground
