A student drops a bowling ball and an apple from a third-story window. Both objects hit the ground at the same time. From the experiment, the student should conclude that
the apple weighs more than the bowling ball
more air friction is acting on the apple than on the bowling ball
gravity pulls on both objects, causing them to fall at the same time.
