Here's why:
* Gravity's Constant Pull: The force of gravity acts on all objects equally, regardless of their mass. This means a heavier object and a lighter object experience the same gravitational acceleration.
* Neglecting Air Resistance: In a vacuum (where there's no air resistance), all objects fall at the same rate. This is because the acceleration due to gravity is constant for all objects.
* Air Resistance's Influence: In the real world, air resistance plays a significant role. Lighter objects, with a larger surface area relative to their weight, experience greater air resistance. This slows them down, making it seem like heavier objects fall faster.
The Experiment: The famous experiment performed by Galileo Galilei demonstrated this principle. He dropped objects of different masses from the Leaning Tower of Pisa, showing that they reached the ground simultaneously (neglecting minor air resistance).
In conclusion: In a perfect vacuum, all objects fall at the same rate, regardless of their mass. In real-world scenarios, air resistance can create the illusion that heavier objects fall faster.
