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

Why does the Earth orbit the Sun and not a planet in the solar system?

• The Sun is more massive than the planets so it's mass causes the gravitational pull.
• It just happened that way.
• The Earth pulls the Sun toward it  because it is so massive.
• The Earth is closer than the other planets so the distance causes the gravitational pull.

How does the Moon's gravity cause the rise and fall of Earth's ocean levels?

• The Sun's gravitational force "pulls" on both the Earth and the Moon at different times.

• Earth revolves on its axis, which causes ocean levels to rise facing the Moon.

• Since the Moon has more mass than Earth, the Moon's gravity causes tides.

• The Moon's gravitational force "pulls" on the oceans
