If a feather and a ball are dropped at the same time from the same height on Earth, why would the ball land first?

• Because the feather was lighter

• Because gravity acts equally on all objects regardless of their mass

• Because the ball could increase in speed as it fell.

• Because the feather was affected by air resistance.
