Describe why a bowling ball and a baseball dropped off of a cliff at the same time would land at different times, but they would land at the same time in a vacuum.

When a bowling ball and a baseball are dropped off of a cliff at the same time, they will land at different times due to the effects of air resistance. The bowling ball is much denser and heavier than the baseball, so it will experience more air resistance and will fall more slowly. In a vacuum, there is no air resistance, so the bowling ball and the baseball will fall at the same rate and land at the same time.
