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.

The force of gravity is related to the masses of objects attracting each other. Which planet has the greatest mass?

• Mercury 3.7

• Jupiter 23.1

• Neptune 11.0

If a feather and a hammer are dropped at the same time on the moon, where there is no atmosphere, which one will hit the ground first?

• Neither, there is no gravity on the moon.
• hammer because it has more mass
• feather because it has less mass
• both will hit at the same time
