Orbital Mechanics - Chapter Summary

Get all the information you need to know about orbital mechanics in one convenient location with help from this chapter. Video lessons provide a comprehensive overview of this subject area by closely examining topics that include circular velocity, gravitational potential energy and geostationary orbit. Review these lessons at your own pace. In no time, you will be able to:

  • Discuss the life of Johannes Kepler and his three laws of planetary motion
  • Define and discuss the importance of the law of universal gravitation
  • Exhibit an ability to calculate acceleration due to gravity
  • List ways mass and distance impact gravity
  • Explain the meaning of gravitational potential energy
  • Describe circular and escape velocity, open and closed orbits, and geosynchronous satellites
  • Differentiate between sun-synchronous orbit and geostationary orbit

Study these concepts your way by accessing lessons in their video or full transcript formats. Videos appeal to individuals who learn with help from visual effects, while transcripts work well for individuals who like to read or print their study materials. No matter your format of choice, the entertaining lessons make learning about orbital mechanics fun! With each lesson is a short quiz designed to assess your comprehension of concepts covered. A practice exam is also available to gauge your knowledge of the entire chapter.

Kepler's Three Laws of Planetary Motion

1. 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!

The Law of Universal Gravitation: Definition, Importance & Examples

2. 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.

Calculating Acceleration Due to Gravity: Formula & Concept

3. Calculating Acceleration Due to Gravity: Formula & Concept

You have no doubt seen gravity work in your life. After all, it is the force that keeps your feet on the ground! This lesson explores the acceleration a body experiences due to gravity and provides details of the mechanics behind it.

The Effects of Mass & Distance on Gravity

4. The Effects of Mass & Distance on Gravity

Does gravity have you down? Well, you are not alone. Gravity is the force that pulls objects with mass toward each other. It is what holds you to the earth. Learn how the strength of gravity is affected by mass and distance.

Gravitational Potential Energy: Definition, Formula & Examples

5. 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.

Circular Velocity & Escape Velocity

6. 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.

Sun-Synchronous Orbit vs. Geostationary Orbit

7. Sun-Synchronous Orbit vs. Geostationary Orbit

After watching this video, you will be able to explain what sun-synchronous and geostationary orbits are and why they are useful. A short quiz will follow.
