Question

which relationship would a scientist most likely model using calculations based on the law of universal gravitation? 1. the motion of planets within the solar system 2. the internal structure and position of the moon 3. factors that affect earths atmosphere and climate 4. natural events that change the shape of earths surface

Explanation:

The law of universal gravitation describes the gravitational force between two masses. The motion of planets in the solar system is governed by gravitational interactions (e.g., between the Sun and planets, or between planets and their moons). The internal structure of the Moon (option 2) is not related to gravitational force modeling for motion. Factors affecting Earth’s atmosphere (option 3) involve meteorology/climate science, not universal gravitation. Natural events changing Earth’s surface (option 4) involve geology (e.g., erosion, tectonics), not gravitational motion modeling. So the motion of planets (option 1) is most likely modeled with universal gravitation.

Answer:

1. the motion of planets within the solar system
