Here's why:
* Newton's Law of Universal Gravitation: This law states that every particle of matter in the universe attracts every other particle with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
* Constant Gravitational Field: Near the Earth's surface, the gravitational field can be considered relatively constant. This means that the force of gravity acting on an object is essentially the same for all objects, regardless of their mass.
* Acceleration due to Gravity: Since force is equal to mass times acceleration (F=ma), and the force of gravity is the same for all objects, the acceleration due to gravity (g) is also the same for all objects.
Important Note: This is true only in a vacuum. In reality, air resistance plays a significant role, affecting the acceleration of objects in freefall. Lighter and larger surface area objects experience greater air resistance, which slows them down. This is why a feather and a bowling ball fall at different rates in the air.
