Gravity influences the motions of celestial objects. The force of gravity between two objects in the universe depends on their masses and the distance between them.
Students will understand and apply scientific concepts, principles, and theories pertaining to the physical setting and living environment and recognize the historical development of ideas in science.
The Earth and celestial phenomena can be described by principles of relative motion and perspective.
Explain complex phenomena, such as tides, variations in day length, solar insolation, apparent motion of the planets, and annual traverse of the constellations.
Most objects in the solar system are in regular and predictable motion.
