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!
What else can I help you with?
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.
Why do a feather and a hammer fall at the same speed in a vaccum?
In a vacuum, air resistance is eliminated, and all objects fall due to gravity alone. The acceleration due to gravity is the same for all objects regardless of their mass, so they fall at the same speed in a vacuum.
A feather and a coin dropped in a vacuum fall with equal?
In a vacuum, there is no air resistance to slow down the falling objects. Therefore, both the feather and the coin will fall at the same rate, reaching the ground at the same time. This is known as the principle of equivalence in free fall.
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?
A coin falls faster than a feather because of a difference in their air resistance. The feather experiences more air resistance due to its larger surface area compared to the coin, causing it to fall slower. The coin's smaller surface area allows it to overcome air resistance more easily and fall at a faster rate.

Which of newton laws apply when a coin hit the ground faster than a feather?
Newton's First Law (law of inertia) and Second Law (F=ma) apply when the coin hits the ground faster than a feather. The coin's greater mass means it requires more force to overcome inertia and fall faster than the feather. The acceleration of the coin is greater due to the larger force acting on it compared to the feather.

The coin's smaller surface area allows it to overcome air resistance more easily and fall at a faster rate.
Why the coin touches the ground first than a feather?
The coin falls faster than a feather due to differences in air resistance. The coin is denser with less air resistance, allowing it to fall quickly. The feather, being less dense and having more air resistance, falls more slowly.
In free falling resistance is more effective in slowing a feather than a coin why?
Resistance is more effective in slowing down a feather compared to a coin in free fall because of the feather's larger surface area and lower density. The increased surface area of the feather allows for greater air resistance to act upon it, slowing it down more effectively than the denser and smaller coin.
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.
What force causes the coin to fall to the ground and describe it?
The force that causes the coin to fall to the ground is gravity. Gravity is a natural force that pulls objects towards each other, in this case, the coin towards the Earth. It is responsible for the acceleration of objects in free fall.
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.
