* Air Resistance: Air resistance is a major factor in how fast something falls. Objects with a larger surface area relative to their weight experience more air resistance.

* Shape: A golf ball is denser and smoother than a ping pong ball. This means the golf ball cuts through the air more easily, experiencing less air resistance.

* Weight: The golf ball is significantly heavier than the ping pong ball. This means gravity has a stronger pull on it, accelerating it faster.

In a vacuum, where there is no air resistance, both balls would fall at the same rate due to gravity's constant acceleration. However, in the real world, the golf ball wins the race to the ground.
