Here's why:
* Newton's Law of Universal Gravitation: The force of gravity between two objects depends on their masses (m1 and m2) and the distance (r) between them: F = G(m1*m2)/r².
* Acceleration due to Gravity: When an object falls towards Earth, the force of gravity acts on it. This force causes the object to accelerate. The acceleration due to gravity (g) is calculated by: g = G*M/r², where M is the mass of Earth, and r is the distance from the object to Earth's center.
* Constant g: Notice that the mass of the falling object (m1) is not part of the equation for g. This means the acceleration due to gravity is the same for all objects, regardless of their mass.
However, in real-world scenarios, air resistance can affect the falling motion of objects.
* Air resistance: This force depends on the object's shape, size, and velocity.
* Heavier objects: Heavier objects tend to have more inertia and resist the effects of air resistance better than lighter objects.
Therefore, in reality, a heavier object will fall faster than a lighter object, but only because air resistance affects them differently.
In a vacuum, where there is no air resistance, both a feather and a bowling ball would fall at the same rate and reach the ground simultaneously.
