• Doubles

• Cut in Half

• Quadruples

• 4x Smaller

2. If I double the distance between two objects, what happens to their gravitational Force?

• 4x bigger

• 2x bigger

• 4x smaller

• 2x smaller

3. What happens to Gravitational force if I double both of the masses but don't change their distance?

• doubles

• half as big

• 4x bigger

• 4x smaller

4. If the mass of Mars is 6.4 kg x 10²³ kg and the mass of Earth is 6.0 kg x 10²⁴ kg, which one would you weigh more on?

• Earth

• Mars

5. Complete the following statement: The farther away two planets are the _______ the gravitational force between them.

• more

• dosen't matter

• same

• less

6. What is gravitational force?

• a force that attracts any object

• a force that pushes any object

• a force that shrinks any object

• a force that enlarges anyobject

7. What is the Universal law of gravitation equation?

• G=F ⋅ m⋅m2/r²

• F=G ⋅ m⋅m₂/(r)²
