Activities
- What two factors affect the gravitational pull between two objects?
- How does the Sun’s force of gravity on Earth compare to its force of gravity on Saturn?
- José said that the Sun exerts a greater force on the Earth than the Earth exerts of the Sun. Do you agree or disagree with his statement? Use facts to defend you thinking.
Answer Key/Rubric
- The masses of the objects and the distance between the objects affect the gravitational pull between them.
- Acceptable responses may include, but are not limited to:
- The Sun pulls on both Earth and Neptune with the same force.
- Neptune has a larger mass than Earth.
- Neptune is farther away from the Sun than Earth.
- The gravitational pull between two objects is affected by the mass of the two objects and the distance between them.
- In terms of distance, the gravitational force between the Sun and Neptune is less than the gravitational force between the Sun and Earth because of they are much farther apart.
- In terms of mass, the gravitational force between the Sun and Neptune is greater than the gravitational force between the Sun and Earth because of they are much more massive.
- Acceptable responses may include, but are not limited to:
- José is incorrect.
- Newton’s third law states that every time one object exerts a force on another object, the second object exerts a force that is equal in size and opposite in direction back on the first object.
- Therefore, the Sun and Earth exert equal forces on each other.
- If the Sun exerted a greater force, the Earth would be pulled toward the Sun.
- If the Earth exerted a greater force, the Sun would be pulled toward the Earth.
- In both cases, the two bodies would collide and one or both would be destroyed.
