Ch 27: Celestial Orbit Characteristics

About This Chapter

Watch video lessons and explore the characteristics of celestial orbits. Get equations for finding an object's speed and period while in elliptical orbit. Let our instructors guide you through planetary motion concepts and celestial object trajectories as well.

Celestial Orbit Characteristics - Chapter Summary

Use our engaging videos in this chapter to refresh or improve your understanding of celestial orbits and objects. Our lessons explain how certain factors impact orbits and break down the concepts in Kepler's planetary motion laws. You'll also study parabolas, ellipses and other trajectories of celestial objects. By the time you finish the chapter, you should be able to:

  • Determine the speed and period of objects in elliptical orbit
  • Describe how gravity and energy influence orbits
  • Explain Kepler's Laws of Planetary Motion
  • Identify the types of trajectories for celestial objects

If you've got around 5-10 minutes, then you've got time to learn about celestial orbits with our video lessons. Each video is brief, straightforward and filled with fun images and animations.

The videos, which you can watch on your mobile device when convenient, also contain tags so that you can jump around to review important concepts. The lessons includes transcripts as well as multiple-choice quizzes for you to assess your grasp of these science topics.
