About This Chapter
How It Works:
- Identify the lessons in the ScienceFusion Gravity in the Solar System chapter with which you need help.
- Find the corresponding video lessons with this companion course chapter.
- Watch fun videos that cover the gravity in the solar system topics you need to learn or review.
- Complete the quizzes to test your understanding.
- If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.
Students will learn:
- To understand the types of energy involved with planetary motion
- The life story and accomplishments of Johannes Kepler
- The law of universal gravitation
- To understand and explain centripetal force
- To describe the theories surrounding the formation of our solar system

1. How Orbits Are Influenced by Gravity & Energy
This lesson will explain how potential energy, kinetic energy, speed, and gravity are linked to the orbital motion of planets in our solar system. It will also define aphelion and perihelion.
2. Kepler's Three Laws of Planetary Motion
Find out about the interesting life and major contributions of Johannes Kepler. This lesson will also teach you how to find out how long it takes a planet to revolve around the sun!
3. The Law of Universal Gravitation: Definition, Importance & Examples
Gravity is what pulls us toward Earth, but it's also what pulls Earth toward us. This is explained by the law of universal gravitation, which describes how all objects in the universe have this important force between them.
4. Centripetal Force: Definition, Examples & Problems
After watching this video, you should be able to explain what centripetal force is, identify the centripetal force in a particular situation, and solve problems using the centripetal force equation. A short quiz will follow.
5. The Solar Nebula Theory: Formation of the Solar System
This lesson will go over the theory that explains how the solar system formed, what theory had once competed with it, and what important implication this theory carries.
