How does changing the mass of objects from Experiment 1 to Experiment 2 affect their gravitational attraction?

• The gravitational force increases with an increase in mass.

• The gravitational force decreases with an increase in mass.

• The gravitational force remains constant regardless of mass.

A student is using a computer program to model the formation of a solar system. In the model, which TWO factors most directly influence the strength of gravitational interactions between forming planets?

In a computer simulation, a student observes the gravitational pull between two planets. If Planet X has three times the mass of Planet Y and the distance between them is the same, how will the gravitational force between the two planets change compared to when Planet X and Planet Y have equal mass?

• The gravitational pull will be three times stronger, as gravitational force is directly proportional to mass.

• The gravitational pull will be nine times stronger because gravitational force is proportional to the square of the mass.

• The gravitational pull will be weaker because a larger mass reduces the gravitational attraction.

• The gravitational pull will remain unchanged because mass does not affect gravitational force.

A student is studying the orbits of planets in our Solar System. Which statement best explains why the inner planets (Mercury, Venus, Earth, and Mars) orbit the Sun faster than the outer planets (Jupiter, Saturn, Uranus, and Neptune)?

• The inner planets have stronger magnetic fields.

• The outer planets are slowed down by more moons.

• The Sun's gravitational pull is stronger on the inner planets.

• The inner planets have less atmospheric resistance.

A student is examining a physical model of a planet's gravitational field using iron filings on a flat surface with a magnet underneath. If the student replaces the original magnet with a stronger one to represent a more massive planet, how would the pattern of iron filings change?

• The iron filings would spread out more evenly.

• The iron filings would cluster more tightly around the center.

• The pattern of iron filings would remain unchanged.

• The iron filings would form a perfect circle around the magnet.
