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.

• It makes objects that are moving stop.
• The force of attraction between two objects.
• It pulls you into space.

A baseball and bat are on the ground.   What is true?

• They attract each other with equal gravitational force.
• There is no gravitational force between them.
• The baseball will float because it's lighter.
• The bat will pull the baseball closer to itself.
