Air Resistance:
* In reality: Air resistance plays a significant role. Lighter objects experience more air resistance relative to their weight, slowing them down more than heavier objects. This is why a feather falls much slower than a rock.
* In a vacuum: If you were to drop the objects in a vacuum (like on the moon), where there's no air resistance, they would fall at the same rate and land simultaneously. This is because gravity exerts the same force on all objects, regardless of their mass.
Galileo's Experiment:
Galileo famously demonstrated this principle by dropping objects of different masses from the Leaning Tower of Pisa. While the story is likely an embellishment, it highlights the idea that in the absence of air resistance, gravity affects all objects equally.
The Key Concept:
The acceleration due to gravity (approximately 9.8 m/s²) is constant for all objects near the Earth's surface. This means that regardless of mass, all objects will gain speed at the same rate as they fall.
However, the initial velocity and air resistance can significantly affect the time it takes for objects to reach the ground.
