• mass and distance 
• mass and matter
• distance and weight 
• weight and mass

Why is the earth's gravity stronger than the moon's gravity?

• The earth is more massive than the moon.
• The moon is so far away from the Earth.
• The moon has no mass.
• The Earth has a larger volume than the moon.

According to Newton's laws, what might happen to the earth if its orbit moved farther away from the sun?

• The Sun's gravitational pull on the earth would increase.
• The Earth's gravitational pull on the moon would increase.
• The Sun's gravitational pull would stay the same.
• The Sun's gravitational pull would decrease.

A person would weigh less on on the Moon than on the Earth because . . .

• Moon has more mass, and therefore more gravity
• Moon has less mass, and therefore more gravity
• Moon has more mass, and therefore less gravity
• Moon has less mass and therefore less gravity

• Ball
• Earth

Where would you have more mass, on Earth or on the Moon?

• Earth
• Moon
• IS THE SAME, mass DOESN'T CHANGE
• In both Planets.
