If they are dropped from the same height, they will fall at equal velocities because there is no air resistance and their accelerations by gravity are equal.
the feather falls faster. The quarter falls faster if the height is very tall. When the hight is about a foot or so the feather falls faster. Try it for yourself :)
1. when you drop a feather and a hammer the feather falls slower than the hammer
The feather is light, so it falls slow. The stone is heavier, so it falls faster.
Because the feather has a massive amount of air resistance. The coin is small and dense, so it falls through the air much easier.
Inside a safe dropped from a plane.If there were a very good vacuum to drop them in, it would be close. The air resistance of a feather limits its falling velocity more than the resistance on the hammer. When the drag caused by friction equals the weight of the object, it cannot continue to accelerate and falls at a speed called its terminal velocity.

Because the moon has essentially no atmosphere, there would be no drag on the feather when it falls. On earth, it would be quite a different matter. The significant surface area of the feather means that as it falls, the friction of the air on it provides significant opposing force to it as it falls. In the case of a falling hammer, the opposing force of air friction on the hammer is negligible compared to the force of gravity on it since the hammer is much heavier than the feather. Since there would be no drag on either item when dropped on the moon, the only force acting on either would be gravity and their acceleration would be only that of gravity with no opposing force to slow them down as they fell.
In simple theory any object will accelerate downwards at the same rate after being dropped. But, if you try it, the air gets in the way and stops a feather falling as fast as a hammer. On the Moon there is no air so everything falls at the same rate (which is 1/6 as fast as on the Earth.

Both the hammer and the feather will hit the lunar surface simultaneously. In the absence of any atmosphere, there is no air resistance to slow down the feather. Therefore, in a vacuum, all objects fall at the same rate regardless of their mass. This was famously demonstrated during the Apollo 15 mission in 1971 by astronaut David Scott, who dropped a hammer and a feather on the moon's surface and observed them falling together.
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.
The duration of Four Feather Falls is 780.0 seconds.
