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.
What are the factors that effect air resistance?
The factors that affect air resistance include the speed of the object (higher speed leads to greater air resistance), the surface area of the object (larger surface area experiences more air resistance), the shape of the object (streamlined shapes experience less air resistance), and the air density (higher air density increases resistance).
When an object fall through the air and encounters air resistance its overall speed will be than if it had not encountered air resistance?
Slower. Air resistance acts in the opposite direction to the motion of the object, reducing its speed as it falls.
When air resistance is not negigble how does return speed compare with the initial speed?
When air resistance is not negligible, the return speed of an object will be slower than the initial speed because air resistance acts in the opposite direction of the object's motion, slowing it down. This results in a decrease in the object's speed over time.
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.

Slower. Air resistance acts in the opposite direction to the motion of the object, reducing its speed as it falls.
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.

What is air resistance and what are the two factors that air resistance depends on?
Air resistance is the force that opposes the motion of an object through the air. It depends on the speed of the object and its surface area exposed to the air.
How does are resistance effect speed?
Resistance can decrease speed by slowing down the movement of an object. In the case of air resistance, for example, the force of air pushing against an object moving through it can reduce speed. Increased resistance requires more energy to overcome, which can lead to a slower speed.
Why can a projectile maintain a constant horizontal speed when neglecting air resistance?
When air resistance is neglected, there are no horizontal forces acting on the projectile to change its speed. According to Newton's first law, an object in motion will remain in motion with a constant velocity unless acted upon by an external force. Therefore, the projectile will maintain a constant horizontal speed in the absence 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.
What three factors affect the amount of air esistance on an object?
The three factors that affect the amount of air resistance on an object are the object's speed (faster speed leads to higher air resistance), the object's size and shape (larger or less streamlined shapes experience higher air resistance), and the air density (higher air density increases air resistance).
Which causes an object to change its speed?
An object changes its speed when an external force is applied to it. This force can either increase or decrease the object's speed depending on its direction and magnitude. Factors such as friction, air resistance, and gravity can also influence the object's change in speed.
