To demonstrate that all bodies in a vacuum fall with the same acceleration due to gravity, we can conduct the following experiment:
1. Set up a vacuum chamber with a transparent side so that the experiment can be observed.
2. Place two objects of different masses (such as a feather and a metal ball) at the top of the vacuum chamber.
3. Create a vacuum inside the chamber to eliminate air resistance.
4. Release both objects simultaneously and observe their motion as they fall towards the bottom of the chamber.
5. Measure the time it takes for each object to reach the bottom of the chamber.
6. Calculate the acceleration of each object using the formula: acceleration = 2 * distance / time^2.
7. Compare the accelerations of the two objects and observe that they are the same, demonstrating that all bodies in a vacuum fall with the same acceleration due to gravity.
This experiment confirms Galileo's famous experiment at the Leaning Tower of Pisa, which showed that objects of different masses fall at the same rate in the absence of air resistance.

Materials:
- Evacuated glass tube
- Two objects with different masses (e.g., a steel ball and a feather)
- Stopwatch
Procedure:
1. Place the evacuated glass tube upright on a flat surface.
2. Hold the two objects side by side at the same height above the bottom of the tube.
3. Release both objects simultaneously.
4. Start the stopwatch as the objects begin to fall.
5. Stop the stopwatch when the objects hit the bottom of the tube.
Observations:
- Both objects fall to the bottom of the tube at the same time, regardless of their mass.
Explanation:
In the absence of air resistance (in the evacuated tube), all objects fall with the same acceleration due to gravity. This is known as the principle of equivalence. The acceleration due to gravity (g) is approximately 9.8 m/s².
The time taken for an object to fall a distance h is given by:
```
t = √(2h/g)
```
Since g is the same for all objects in a vacuum, the time of fall will be the same for objects of any mass.
Conclusion:
The experiment demonstrates that all bodies in a vacuum fall with the same acceleration due to gravity, regardless of their mass. This supports the principle of equivalence and highlights the universality of gravitational force.
