They fall at the same rate.
This is one of the most fundamental concepts in physics, famously demonstrated by Galileo Galilei. Here's why:
* Gravity's Constant Acceleration: The force of gravity acts equally on all objects, regardless of their mass. This means that every object experiences the same acceleration due to gravity (approximately 9.8 m/s² on Earth).
* Neglecting Air Resistance: In a vacuum, where air resistance is absent, all objects will fall at the same rate and reach the ground simultaneously. This is because the acceleration due to gravity is the only force acting on them.
The Role of Air Resistance:
* In reality, air resistance plays a significant role. This force opposes the downward motion of an object and is proportional to the object's surface area and velocity.
* Objects with larger surface areas and lower densities (like feathers) experience more air resistance and fall slower. Objects with smaller surface areas and higher densities (like a rock) experience less air resistance and fall faster.
The Takeaway:
While heavier objects have a stronger gravitational force acting on them, this is exactly balanced out by their larger inertia (resistance to change in motion). The net effect is that both heavy and light objects fall at the same rate in a vacuum.
