About This Chapter

Dive into this chapter on the physics of space to review details about the moon, planets of the solar system, space probes, and more. The brief lessons in this chapter are a convenient and valuable resource to use when you are preparing for a test or working on class assignments.

Physics of Space - Chapter Summary

As you go through these lessons on the physics of space, you can review details about Earth's axial tilt and the reason for astronomical ways of measuring distance. Your review of this chapter will boost your comprehension of space probes and what causes an eclipse. By the end of your studies, you should be ready to:

  • Describe Earth's place in the solar system and the universe
  • Discuss Earth's orbit around the sun
  • Explain why different seasons occur
  • List facts about the moon
  • Differentiate between mass and weight
  • Explain how gravity plays a role in forming the shapes of planets
  • Recall planets in the solar system that can be seen with the naked eye
  • Distinguish between natural and artificial satellites

The self-assessment quizzes available for each lesson will test how much you know about the physics of space. These engaging lessons can help you easily understand the topics presented. You can review all the lessons in order, or just those where you require a refresher.
