write the main causes of Galileo Feather and coin experiment.
Answers
Answer:
In a vacuum, the objects fall at the same rate independent of their respective masses. That means coin and feather both reach ground at same time in a vacuum. Larger objects experience more air resistance than smaller objects. Also, the faster an object falls, the more air resistance it encounters.

Answer:
1. This experiment lets you repeat Galileo's experiment in a vacuum.
2. The free fall of a coin and feather are compared, first in a tube full of air and then in a vacuum.
3. With air resistance, the feathers fall more slowly. In a vacuum, the objects fall at the same rate independent of their respective masses.
4. Galileo predicted that heavy objects and light objects would fall at the same rate. The reason for this is simple.
5. Suppose the coin has 50 times as much mass as the feather. This means that the earth pulls 50 times as hard on the coin as it does on the feather.
6. Galileo proved that gravity pulls on all objects equally.
7. He proved this by dropping two objects of the same size but different weights, such as a lead ball and a wooden ball.
8. Most historical records indicate that Galileo himself probably never performed this experiment, although he discussed the ideas.
