Only in an airless environment. Gravity pulls feathers, pennies, hammers and even giant objects at the same rate of acceleration, but we observe feathers to fall slower because feathers catch air, giving resistance to simply falling straight down whereas pennies are dense and smooth, catching relatively little air.
David Scott, an astronaut on the Apollo 15 mission which landed on the moon, conducted an experiment and confirmed the theory by dropping a hammer and a feather on the moon's surface; both were dropped from the same height and both struck the "ground" (the moon's surface) at the same time because the moon has no air to resist the moon's gravitational pull on the feather the way the Earth does on the surface of our planet.

A penny and a feather that are dropped from the same height at the same time will?
The penny will land first, because the feather displaces the air. That is also why a boat floats, it displaces enough water underneath it that the displaced water pushes up keeping the boat afloat.
Why the coin touches the ground first than a feather?
Air drag. They would fall at the same speed in a vacuum.
Would a feather fall faster than a stone in a vacuum?
No, they would fall at the same speed, as there exists no air-resistance. They would accelerate at the same tempo and hit the ground at the same time.
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.
Does the size of the ball effect how fast it falls?
Everything falls at the same speed. the only variable is drag. For instance a feather & a bowling ball would fall at the same speed in a vacuum, but not through the air.

both will fall at the same time

Why do some objects fall at a different rate than others?
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.
What is the meaning of knock you down with a feather?
it means that you have been so shocked that if someone tapped you with a feather you would fall down
In the absence of air a penny and a feather that are dropped from the same height at the same time will fall at which speeds relative to each other?
Relative to each other . . . zero speed.Relative to you watching them fall . . . equalspeeds.
Do all object hit the ground at the same time?
Of Course Not!! If you drop say a feather... it takes sometimes a while... but if you drop a heavy thing water buckets it take shorter!But that's because a feather drifts through the air, not because of its weight. If the only factor is gravity (no wind, no friction etc.), all objects fall at the same speed. So a penny and an elephant would hit the ground at the same time.
Why does a penny fall faster than a feather is it because gravity acts less on a feather?
Purely air resistance, the feather floats on the air. The mass is irrelevant. If a penny was dropped at the same time as a brick (ignoring wind resistance) both would hit the ground at the same time. Look up Galileo's tower of Pisa experiment. http://en.wikipedia.org/wiki/Galileo%27s_Leaning_Tower_of_Pisa_experiment This also includes a video of a feather and a hammer being dropped on the moon (where there is no air). Both hit the ground together.
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.
