Jupiter has about 317 times more mass than Earth. What can you infer from this fact? 

• That Jupiter’s gravitational force is much weaker than on Earth’s gravitational force.

• That Jupiter’s gravitational force is much stronger than Earth’s gravitational force.

• That Jupiter’s and Earth’s gravitational forces are equal.

• Mass has no effect on the gravitational force between two objects

This type of force resist motion between two surfaces that are pressed together

• contact

• gravity

• friction

If both forces are going in the same direction you should______ those forces

• Add

• Subtract

• Divide

• Multiply
