A modern approach to Galileo Classic Experiment

Galileo's famous experiment at the Leaning Tower of Pisa was conducted to demonstrate that objects of different masses fall to the ground at the same rate in the absence of air resistance. A modern take on this experiment could use a Guinea (a coin) and a feather, instead of the cannonballs Galileo used in his experiment.

To recreate this experiment, you would need a vacuum chamber to eliminate air resistance. Place a Guinea and a feather at the top of the vacuum chamber and remove all air from the chamber. Once the vacuum has been established, simultaneously release Guinea and the feather.

Without air resistance, both objects should fall to the bottom of the chamber at the same rate. This experiment helps to illustrate the principle of inertia, which states that objects at rest tend to stay at rest, while objects in motion tend to stay in motion unless acted upon by an external force.

It is worth noting that the experiment is not possible in the Earth's atmosphere because air resistance would cause the feather to fall more slowly than Guinea.

A way of investigating the experiment is by changing the surface area of an object can be used to recreate Galileo's experiment and demonstrate the principle of air resistance. This is because air resistance depends on the surface area of an object, as well as its speed and shape.

To recreate the experiment, you could use two objects with the same mass but different surface areas, such as a flat piece of paper and a crumpled piece of paper. Hold the two pieces of paper at the same height and release them simultaneously. You will observe that the flat piece of paper falls more slowly than the crumpled piece of paper, as it experiences more air resistance due to its larger surface area.

This demonstrates the same principle that Galileo discovered with his Leaning Tower of Pisa experiment. In the absence of air resistance, both objects would fall to the ground at the same rate due to the principle of inertia. However, the presence of air resistance causes the objects to fall at different rates due to the differences in their surface areas.
