About This Chapter
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.
1. Elliptical Orbits: Periods & Speeds
After watching this lesson, you will be able to explain what an elliptical orbit is and calculate the period and speed of an object in an elliptical orbit, if given enough information. A short quiz will follow.
2. 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.
3. Kepler's Laws, Ellipses, and Eccentricity
This lesson will discuss Kepler's First Law of Planetary Motion; define an ellipse, focus, major axis, semimajor axis, and eccentricity; and explain what they have to do with astronomy.
4. The Four Kinds of Trajectories for Celestial Objects
What does the slicing apart of a cone and the resultant shapes have to do with trajectories and escape velocity? This lesson will tell you as it goes over ellipses, circles, hyperbolas, and parabolas.
