Some air resistance examples include walking in the storm, a feather falling to the ground, a paper plane, an airplane, a skydiver using a parachute, and riding a bicycle.
The units for the force of air resistance are in Newtons (N).
force of gravity is greater than air resistance .
To keep the topic simple, it can be said that the two most common factors that have a direct effect upon the amount of air resistance are the speed of the object and the cross-sectional area of the object. Increased speeds result in an increased amount of air resistance.
Two ways to reduce air resistance are stated: reducing the area in contact with air (by the cyclist ducking down or cycling behind someone else) and by being more streamlined (wearing smoother surfaces or a more streamlined helmet).
The air resistance's direction will be in the opposite direction as the moving object's velocity. When an object moves in a downward direction, the drag force acts in an upward direction, whereas the drag force is downward if the object moves in an upward direction.
Air resistance is fluid friction. Fluid friction is the friction experienced by objects which are moving in a fluid and the air is a fluid.

How does air resistance impact the terminal velocity of falling objects, and what factors determine the rate at which an object reaches this velocity?

Replying to

Air resistance decreases the rate of acceleration of an object by counteracting the force of gravity. Over time, due to air resistance, a falling object will no longer accelerate and reach its terminal velocity, when there is zero acceleration.

Air resistance exerts a frictional force against the moving body. As a body moves, air resistance decelerates it down.
Friction is a force that opposes the motion of objects; friction can cause objects to slow down. Air resistance is a type of friction. Air resistance causes moving objects to slow down.
At terminal velocity, air resistance equals in magnitude the weight of the falling object. Because the two are oppositely directed forces, the total force on the object is zero, and the speed of the object has become constant.
It is better to send air particles around and over the vehicle, rather than underneath where it can push the vehicle up and interfere with its ability to stick to the road. This also gives them a smaller frontal area, reducing the amount of resistance generated.
