They will hit the ground at the same time.
Why?
* Gravity's Constant Acceleration: The acceleration due to gravity (approximately 9.8 m/s²) is constant for all objects, regardless of their mass. This means that both balls will speed up at the same rate as they fall.
* Independent Motion: The force of gravity acts on each ball individually. The mass of one ball doesn't influence the motion of the other ball.
The Catch:
* Air Resistance: In reality, air resistance plays a role. Lighter objects experience more air resistance relative to their weight. This means a feather and a bowling ball dropped from the same height won't land at the same time. The bowling ball will hit first.
Experiment:
Try dropping a heavy object (like a coin) and a lighter object (like a crumpled piece of paper) from the same height. You'll see a difference in their times of descent. Now, try dropping the crumpled paper with the coin. You'll likely find they fall together! This demonstrates the influence of air resistance on the outcome.
