Heavy as a rock and Light as a feather. Do Different items fall differently?

More then 2300 years ago, Aristotle (a greek philosopher) claimed that due to the fact that a Rock is heavier from a Feather, the rock will reach ground before the feather if they fall from high level point. 

The phrases "heavier as a rock" and "light as a feather" are linked to Aristotle.  

2,000 years later, in 1604 an Italian scientist name Galileo Galilee claimed  that two objects will reach ground at the same time regardless there shape, weight or any difference in physical dimensions, if there is no friction involved. 

Galileo claimed that the air friction influence the feather falling and not his light weight. 


Use the link below to simulate Galileo's tests with different sizes. 

You can use friction and no friction as well.

Decide who os right, Aristotle or Galileo ?

Aristo was right.
Heavier objects will reach the ground before lighter ones.
Weight has an influence on falling objects.
Bigger objects in size will reach the ground before smaller ones even if the weight are the same.
Lighter objects can reach ground before heavier ones.

The feather will reach ground before the rock.
Galileo was right.
Objects regardless there shapes will reach ground at the same time, no air friction involved.

Interesting question

As a physics student it wasn't an intuitive answer to me as well…

I added a new location to your question - a nice experiment that will help convincing if somebody is still wandering


One improvement suggestion - Try inserting the demo into the section; it's more convenient and user friendly (otherwise one has to leave the site to start the demo).

Please note the correct link to the demonstration

Address the question you wrote

First of all I liked the question and the reasoning process that it requires.
I think there is a mistake on the question itself, and you meant to write: "decide who is right..."
About the simulation is very pleasant and comfortable, I think maybe God headers or comments about each part the simulation.

I would considering to establish the parameters of the simulation to prevent a mistake in choosing the wrong parameter which would lead to resolving the question.
