- 11. Multiple ChoiceIn a normal environment, why does a bowling ball and feather hit the ground at different times when dropped from the same height?They don't; they hit the ground at the same time.One is more dense than the other.One is heavier than the other.Air resistance
- 12. Multiple ChoiceWhich would fall with greater acceleration in a vacuum—a leaf or a stone?the leafthe stoneThey would accelerate at the same rate.It is difficult to determine without more information.

- 14. Multiple ChoiceA ball is thrown upwards and caught when it comes back down. In the absence of air resistance, the speed of the ball when caught would beless than the speed it had when thrown upwards.more than the speed it had when thrown upwards.the same as the speed it had when thrown upwards.
- 15. Multiple ChoiceWhen there is no air resistance, objects of different masses dropped from restfall with equal accelerations and with equal displacements.fall with different accelerations and with different displacements.fall with equal accelerations and with different displacements.fall with different accelerations and with equal displacements.
