What is the shape of the Earth?

• A cone

• A cube

• A dodecahedron

• A sphere

What is the relationship between distance and the strength of gravity?

• The farther apart objects are, the weaker their pull on each other

• The strength of gravity is always the same, regardless of distance

• The strength of gravity is always the same, regardless of distance

What is the relationship between mass and the force of gravity?

• The greater the mass of an object, the greater the force of gravity on that object

• The smaller the mass of an object, the greater the force of gravity on that object

• The mass of an object has no effect on the force of gravity on that object

What is the difference between weight and mass?

• Weight is a measure of the amount of matter in an object, while mass is a measure of the force of gravity on an object

• Weight is a measure of the force of gravity on an object, while mass is a measure of the amount of matter in an object

• Weight and mass are the same thing

• Weight and mass are both measures of the volume of an object

What is one reason that the force of gravity on Earth is important?

• It makes sound travel faster

• It causes objects to repel each other

• It makes the Earth spin on its axis

• It helps keep our atmosphere from drifting away into space
