It reduces the acceleration of the falling object due to friction.

Air resistance creates friction and slows a falling object.

Air resistance causes friction and slows an object.

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 slows the acceleration - possibly down to zero @ "terminal velocity".

It does not affect its acceleration in a vacuum, that is, no air resistance. The acceleration s the acceleration of gravity which is constant

No. If there's any difference in the acceleration of different falling objects, it's the result of air resistance. If you could drop them through a space with no air, the lightest feather and the heaviest rock would have the same acceleration. It's called the acceleration of gravity, and it's 9.8 meters (32.1 feet) per second2 on earth. Regardless of the mass of the falling object.

Acceleration of a falling object is directly proportional tothe force of gravity in the object's location.

the same that it would affect any falling object. The higher the air resistance the thicker the air density. This will result in a higher drag coefficient and will slow the fall of the object.

Absolutely,Although the effect will be minimal if you drop the quarter from waist height.If you drop it from an airplane, it might even reach terminal velocity where the air resistance would counteract and balance the acceleration due to gravity.

Air resistance and gravity are the main components.

There's no mechanism for swapping drawings on WikiAnswers. Suggest you try internet search for terms like 'free fall', 'gravity', 'air resistance', 'terminal velocity', etc.

The force of acceleration (gravity) the drag (resistance which is a complex factor including shape, density, surface structure, viscosity of the medium through which the object is falling, etc. )

Air Resistance slows the fall of an object, and Gravity speeds it up.

Air resistance will determine the "terminal volocity" based on surface area

no, acceleration due to gravity is always the same, although air resistance might affect it

Without propellers, jets, or a parachute, an object can't to anything to affect its acceleration when it's falling. "Free fall" means moving under the influence of gravity only, with not even any air resistance. In that situation, on or near the surface of the Earth, acceleration is constant, regardless of the size, shape, mass, weight, or gender of the falling object. That number is 9.8 meters (32.2 feet) per second2 ... known as the acceleration of gravity on Earth.

The shape of the object and the density of the gas that the object is falling through.

This is called Terminal Velocity. Gravity pulling downwards matches the air resistance pushing upwards to cancel the acceleration out. Many people misunderstand this and believe that this means that the object falling is no longer moving, but it is speaking in terms of acceleration, not speed. So the acceleration from before terminal velocity was reached will still be in affect, but the object will be neither gaining or losing speed.

free fall is a special type of motion in which the only force acting upon an object is gravity. Objects that are said to be undergoing free fall, are not encountering a significant force of air resistance; they are falling under the sole influence of gravity. Under such conditions, all objects will fall with the same rate of acceleration, regardless of their mass.

terminal velocity is the final maximum velocity of a falling object.
