A basketball weighing 22 oz and a tennis ball weighing 5 oz are dropped from the same height. Which would hit the ground first?

• The tennis ball because it is lighter than the basketball and therefore has more gravitational pull.

• The basketball because it is heavier than the tennis ball and has a greater gravitational pull.

• They hit the floor at the same time because the gravitational pull will be the same for both.

• The basketball because the tennis ball has greater air resistance than the basketball.
