Mass doesn't affect air resistance directly. Air resistance is affected by the shape of the object. However, other things (shape, density) being equal, an object with a greater mass will have greater air resistance, simply because it is bigger. On the other hand, the larger object will have a smaller ratio of air resistance to mass, since mass will increase with the third power of the diameter (or any linear measurement), while the surface area - which affects air resistance - will only be proportional to the second power of the diameter. This will make a larger object fall faster.

∙ 10y agoThat depends on the specific circumstances. Air resistance depends on speed. But what usually happens is that an object falls faster and faster, until air resistance is just as large as the force of gravity. In that case, the object doesn't speed up any more, and is said to have reached terminal velocity. If an object is thrown down FASTER than the terminal velocity, air resistance will be greater than gravity; in this case, the object will slow down until, once again, air resistance and gravity are balanced.

If a skydiver jumps out of a plane which force is greater gravity or air resistance?
Gravity
Compare the effects of gravity and air resistance on a falling skydiver before and after she opens her parachute?
-- The force of gravity is unchanged before and after.-- The force of air resistance on the skydiver is greater before, and less after,because she is falling slower after the parachute opens.-- The effect on her of air resistance is greater after the parachute is open. Theincreased air resistance itself acts on the parachute, and its effect is transferredto the skydiver through her harness.
Which encounters the greater force of air resistance a falling elephant or a falling feather?
A falling elephant encounters a greater force of air resistance than a falling feather does. The force of air resistance can't be greater than the weight of the falling object. When the force of air resistance is equal to the weight of the falling object, the object stops accelerating, its falling speed becomes constant, and the force of air resistance doesn't get any bigger. So the force of air resistance against a falling feather can't be greater than the weight of the feather. But the force of air resistance against a falling elephant can be, and undoubtedly is, greater than the weight of a feather.
Why is gravity a bigger force than air resistance?
It isn't, necessarily. But the force of gravity is constant, whereas the force of air resistance depends on how fast you're moving through the air. So when you begin to fall, gravity is stronger, and it makes you fall faster and faster. But as your speed increases, so does the force of air resistance, and eventually, the force of air resistance builds up to be equal to the force of gravity. At that point, you keeep falling, but your speed doesn't grow any more.
What forces act on a falling leaf?
Gravity and air resistance.
If a skydiver jumps out of a plane which force is greater gravity or air resistance?
Gravity
A feather is in freefall when the force of gravity is greater than the force of air resistance is equal to the force of air resistance is less than the force of air resistance is the only force acting?
"Free fall" means that gravity is the only force acting on a body.

When force of gravity is greater than air resistance the object will?
Yes, definitely, so make sure you are not standing under it.
Which direction does the parachutist go if gravity is greater than air resistance?
The parachutist will go down, of course. If gravity is greater than air resistance, then the parachutist would accelerate (his speed would increase). This would increase air resistance, up to the point where gravity and air resistance are in balance.
What force changes when a sky diver's parachute opens?
The force that changes is air resistance and the force that stay the same is gravity.
What two forces act on all falling objects in the earths atmosphere?
Gravity and Resistance Under free fall, the only force acting upon an object is the force of gravity. But realistically, there is also the force of friction from the air (Air Resistance) that opposes the force of gravity.
What do you get when the force of air Resistance from the force of gravity?
The net force on a following object
What is the counter force of an airplane?
Gravity and air resistance.
Do you get when you subtract the force of air resistance from the force of gravity?
Terminal Velocity
