* Gravity's Constant Acceleration: The force of gravity pulls on all objects with the same acceleration, regardless of their mass. This acceleration is approximately 9.8 m/s². This means every second, an object's downward speed increases by 9.8 meters per second.
* Neglecting Air Resistance: In a vacuum, there's no air resistance to slow down the objects. Air resistance is a force that depends on the object's shape and size, and it can significantly affect the time it takes to fall.
* Mass and Acceleration: While a heavier object has more inertia (resistance to change in motion), it also experiences a greater gravitational force. These two factors balance each other out, resulting in the same acceleration for both objects.
Why it seems different in real life:
In reality, air resistance plays a huge role. A feather and a bowling ball dropped from the same height will not fall at the same rate. The feather, with its large surface area and low mass, experiences much greater air resistance, slowing it down dramatically.
Experiment to try:
To see this in action, try dropping two objects with similar shapes but different weights (like a golf ball and a tennis ball) from the same height. You'll likely see them hit the ground at almost the same time!
