What causes a marble to reach the groud first if a feather and the marble accelerate at the same speed?
A marble is more dense and has less surface area, so it is not affected by air resistance as much as the feather.
A feather will fall through the air more slowly that a brick because of?
because of air resistance
Among the feather and the apple which has greater air resistance?
a feather
Why would a feather and an elephant fall at the same time in a vacuum?
Because a feather has more air resistance, it normally falls slower, but in a vacuum, there is not air resistance so they fall at the same rate. Think of it as a feather and an elephant falling in space.
Why does the feather fall more slowly than a hammer do?
On Earth, a feather falls more slowly than a hammer due to air resistance. The feather is impeded more by the air than the bowling ball is. In a vacuum, such as outer space, there is no air and thus no air resistance. In this environment, all objects fall at the same rate, regardless of their shape or mass.
What is the friction of air?
friction in air is called air resistance. When a feather falls through the air, it is slowed down by this air resistance. as gravity pulls the feather down to the earth, air resistance pushes it up. gravity almost always wins, however, when the feather gets enough acceleration to overcome air resistance. the mass of the object effects the amount of air resistance. a feather has low mass, therefore is slowed down by air resistance. A rock has much mass, therefore air resistance doesn't effect it as much. this is why a rock appears to fall "faster" than a feather. take the rock and feather on the moon (something the Apollo astronauts did) and they fall at the same rate.
A feather will fall to the ground more slowly than a brick because of what?
The resistance of the air.
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.
Which force makes a feather fall to the ground more slowly than a stone?
The feather falls slower because it has air restistance. The air pushes up on it. The rock falls faster because it's mass and how it doesn't have air resistance. Also, because toilet seats produce a gas, reacting with the feathers on a feather, making the feather rise.
If there is no air resistance does a feather still fall more slowly than an apple?
Yes it does. Because the apple is still heavier and will get more gravitional pull. And the feather will still weigh less.
What causes a marble to stop moving?
Friction and air resistance.
What forces are acting upon a feather in the air?
Air resistance(AKA drag), gravity
