About This Chapter
Gravitational Laws - Chapter Summary
The lessons in this chapter provide an overview of gravitational laws. You'll review the conditions for launching a satellite as well as the formula for gravitational potential energy. You'll also look at the orbit of planets around the sun. By the end of the chapter, you should be ready to:
- Solve problems using Newton's law of gravitation
- Calculate gravitational potential energy and discuss how it works
- Use equations to calculate circular velocity and escape velocity
- Explain Kepler's three laws of planetary motion
- Discuss stable orbital motion of a satellite
These video lessons help you quickly get up to speed on gravitational laws. Our instructors provide great examples and present the information in a concise manner. Video timelines let you easily navigate to specific topics. A brief multiple-choice quiz is available for each lesson to test your knowledge, and you can print the quizzes for use as worksheets.
1. Newton's Law of Gravitation: Definition & Examples
This lesson explains how gravity works mathematically and teaches you how to use Newton's Law of Gravitation to solve problems. A short quiz will follow.
2. Gravitational Potential Energy: Definition, Formula & Examples
In this lesson, you will learn what gravitational potential is, the equation we use to calculate it, and how to use that equation. We'll look at some real-life examples so you can see how it works. A short quiz will follow.
3. Circular Velocity & Escape Velocity
This lesson will describe the concepts of circular velocity, escape velocity, open orbits, closed orbits, and geosynchronous satellites. It will provide the equations necessary for you to be able to calculate out circular and escape velocity as well.
4. 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!
5. Stable Orbital Motion of a Satellite: Physics Lab
In this lab, you're going to learn about satellites in stable orbital motion. You will set up an experiment to simulate the orbit of a satellite and explore the shapes this orbit can take.
