This is one of Galileo's famous discoveries, and it's a fundamental principle in physics. Here's why:
* Gravity's Constant Pull: Gravity pulls on all objects with the same force, regardless of their mass. This force is what causes objects to accelerate towards the ground.
* Negligible Air Resistance: In a vacuum, there is no air resistance. Air resistance is what slows down objects of different shapes and sizes differently. Without it, the only force acting on the objects is gravity.
Example: If you drop a feather and a bowling ball in a vacuum chamber, they will fall at the same rate and hit the bottom at the same time.
Important Note: This is true only in a vacuum. In the real world, air resistance plays a significant role, causing lighter objects with larger surface areas to fall more slowly than heavier objects.
