Air resistance and gravity are the main components.
-- gravity -- air resistance
Gravity accelerates a falling object.
If there is no air resistance, gravity will accelerate the falling object, that is, it will change its velocity.
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.
It reduces the acceleration of the falling object due to friction.
It counteracts the force of gravity and slows the decent of the object at a rate proportional to the object's velocity.
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.
Nearly all falling object are affected by the resistance of air. However some objects have a mass greater than the air can affect. There is also the case where air resistance equals that of gravity and the object will not fall any faster.
gravity and air resistance
Gravity accelerates falling objects at a constant rate (on Earth, it's 9.8 m/s/s). However, in the presence of air, the air pushes against the falling object, and the faster it's falling then the more air is pushing against it. The point at which the air resistance equals the pull of gravity is called "terminal velocity." It varies by object depending on buoyancy.

Air resistance creates friction and slows a falling object.
the acceleration of gravity is 9.8 m/s
Gravity and air resistance (drag) are the two opposing forces acting on the falling body. Gravity causes the object to accelerate (fall faster) while the air resistance causes the object to decelerate (fall slower). At a certain velocity called the terminal velocity these two forces are in balance and there is no change in falling speed.

reached "Terminal Velocity".
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
The shape of the object and the density of the gas that the object is falling through.
Gravity is one, and I believe that friction is the other. Friction here being caused by the resistance to motion of the fluid the object is falling in. Generally this is termed air resistance or drag and it is related to the object's velocity and cross section as well as the fluid's viscosity.
When a falling object stops accelerating but is falling at a constant velocity, it is called terminal velocity.
