Which ball will be traveling faster when hitting the ground if both are dropped from the same height?

When two objects are dropped from the same height in a vacuum (where air resistance is negligible), they will accelerate towards the ground at the same rate due to gravity, which is approximately 9.81 m/s² on Earth. This means that by the time they reach the ground, they will have the same velocity, regardless of their mass or size.

This situation is based on the principle established by Galileo's experiments, which demonstrated that the acceleration due to gravity is constant and does not depend on the mass of the falling object. Therefore, both balls will hit the ground at the same speed when dropped from the same height.

In real-world scenarios, factors such as air resistance could affect the speed at which objects fall, particularly for objects with significant drag (like a feather or a parachute), but if we assume minimal air resistance, the conclusion holds that both balls will indeed reach the ground at the same speed.
