Explain about coin and feather experiment?
Coin and Feather Experiment
The coin and feather experiment is a demonstration of the effect of air resistance on falling objects. It is also known as the Galileo's experiment since it was first performed by famous Greek astronomer and physicist, Galileo Galilei in the late 16th century. The experiment proved that objects of different masses fall at the same rate in a vacuum, but in the presence of air resistance, they fall at different rates.
Procedure
- A vacuum chamber is required for this experiment.
- The chamber is evacuated to create a vacuum.
- Two objects, a coin and a feather, are dropped simultaneously from the same height inside the vacuum chamber.
- Without air resistance, both objects fall at the same rate and hit the bottom of the chamber at the same time.
- The experiment is repeated in open air, and this time the feather falls much slower than the coin due to air resistance.
Explanation
When dropped in a vacuum, both objects experience the same acceleration due to gravity, which is 9.8 m/s². Therefore, they both fall at the same rate and hit the bottom of the chamber at the same time. However, when dropped in the air, the feather experiences more air resistance than the coin due to its larger surface area. This air resistance acts against the feather's weight and slows it down, causing it to fall slower than the coin.
Significance
The coin and feather experiment is significant because it demonstrates the effect of air resistance on falling objects, which is often overlooked in everyday observations. It also illustrates the concept of gravity and the laws of motion. This experiment has been replicated many times, and it continues to be used as a demonstration in classrooms and science museums around the world.

Explain about coin and feather experiment?
This experiment was done to show the force of friction. Here a coin and a feather were released together from a height. It was observed that the coin reached the ground far more earlier than the feather.
This was happened due to the air friction. As the coin was heavier, it felt less resistance of the air friction. But the feather was lighter so it felt more resistance. And that's why there was a time gap between there contacts to the ground.
The experiment has shown that there exists a resistance power of air friction due to which heavier things reach earlier to the ground when released together from a height.
It was also that, if the experiment would have done in vacuum then both the coin and the feather would have touched the ground at same time, because air friction does not exists in vacuum. In vacuum the weight of the things does not matter.
One can even do this experiment with a big rock and a piece of hair. In this also the above processes will take place.
