Why do a coin and a feather in a vaccum tube fall with the same acceleration?

There IS gravity in a vacuum first of all.
The gravity accelerates both the penny and the feather at the same rate, about 9.81 meters per second.
And since there is no air, there are no frictional forces acting on them, which normally make the feather move slower.
So they go at the same speed!
Hope this helps!

∙ 13y agoThe force of gravity is proportional to an object's mass. Therefore, the acceleration due to gravity is constant on all objects, no matter what their mass is. In a vacuum, a feather will fall at the same speed as an elephant.

2) In free fall, all objects fall with the same acceleration; one way to understand this is that, if one object has twice as much mass as another, there will be twice as much force to accelerate it. To compensate, the object will also have twice as much mass (opposing the acceleration).

Why do a coin and feather in a vacuum tube fall with the same acceleration?
Because the acceleration gravity on Earth is constant, 9.86 m/sec^2.
A feather and a coin dropped in a vacuum fall with equal?
ANSWER: the two objects would have the same velocity, but since KE is proportional to mass, the heavier one would have more KE.
Why does a coin and a feather fall with different accelerations in the presence of air?
The structure of the feather makes it catch the air and fall more slowly than the coin. Refer to the related link for the Apollo 15 mission to the moon, which has no atmosphere, in which an astronaut drops a hammer and a feather at the same time.
Why does a coin fall down faster than a feather?
Because the feather has a massive amount of air resistance. The coin is small and dense, so it falls through the air much easier.
Why the coin touches the ground first than a feather?
Air drag. They would fall at the same speed in a vacuum.

What is the effect of mass of freely falling body on the gravitational acceleration?
No effect whatsoever. Without air to interfere with the effects of gravity, a small feather and a large rock fall with the same acceleration.
Why the coin touches the ground first than a feather?
Air drag. They would fall at the same speed in a vacuum.
How does the acceleration of gravity compare between objects?
Acceleration due to gravity is the same for EVERY object on the earth, at the same altitude. The only thing that differs is the effect other forces have on it. For instance, in a vacuum, a feather and a bowling ball will both fall at the same rate. However, in normal air, the feather will be impeded by air resistance, so will fall slower.
What would happen if you dropped a feather on the moon?
If you drop a feather on the moon, it will fall from your hand with an acceleration of 1.62 meters (5.32 feet) per second2, and never a ripple or a flutter. If you drop the feather and a stone at the same time, they hit the ground on the moon at the same time.
Why do some objects fall at different rates than other?
Objects fall through air at a different rate due to the amount of air resistance. Feathers or dandelion "parachutes" fall at a much slower pace than coins. However there is an experiment called "The coin and the feather". A glass tube about 6cm in diameter has a penny and a penny placed inside before the air is evacuated using a vacuum pump. The tube is then sealed. If the tube is held vertically the coin and feather are both at the bottom. If the tube is then swiftly inverted, so that what was bottom becomes top, the coin and feather are seen to fall at the same rate. Unbelievable unless you actually see it.
Can a quarter and a feather fall at the same speed?
theoritically yes. if they are placed in a vacuum packed room with no air, just empty space, they can fall at the same rate. if they fell in air, the aerodynamics wouldn't equal out, so the quarter would fall faster.
When nothing but gravity is affecting the fall of an obeject it is said to be in?
A Vaccum Also called free-fall.
Does mass determine the acceleration due to gravity?
The acceleration due to Gravity is constant at 32 feet per second per second, if you dropped a feather and a cannon ball in a vacuum they would fall at the same rate and hit the floor at he same time.
