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

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

Do planets affect the sun? Why?

• No. Sun pull on the planets and keep them in orbit.
  
• Yes. Sun pulls on planets, planets pull on Sun

What is gravitational force?

• It makes objects at rest start moving.
• It makes objects that are moving stop.
• The force of attraction between two objects.
• It pulls you into space.

A student drops a bowling ball and an apple from a third-story window. Both objects hit the ground at the same time. From the experiment, the student should conclude that

• the apple weighs more than the bowling ball

• more air friction is acting on the apple than on the bowling ball

• gravity pulls on both objects, causing them to fall at the same time.

Which of the following data would support the claim that the gravitational force between objects depends on mass?

• A rocket can escape Earth’s gravity by traveling at high speed.

• Gravitational force is stronger on more massive planets.

• The further a planet is away from the sun, the smaller the gravitational force.

• An object’s weight can change depending where it is on Earth.
