About This Quiz & Worksheet

Each of the trajectories discussed have distinct characteristics, and this quiz/worksheet combination will help test your knowledge of the trajectories and how they are informed by the velocity of the object in orbit. Topics on the quiz include the four trajectories and the concept of escape velocity.

Quiz & Worksheet Goals

In these assessments, you'll be tested on:

  • Open curves
  • A closed elongated curve
  • The result of an object traveling at or above escape velocity
  • Minimum speed to escape a gravitational attraction

Skills Practiced

This quiz and worksheet will allow you to test your skills in the following areas:

  • Reading comprehension - ensure that you draw the most important information on the four types of trajectories discussed in the related lesson
  • Defining key concepts - ensure that you can accurately define the different trajectories explained in the lesson
  • Distinguishing differences - distinguish between the four types of trajectories discussed in this lesson
  • Knowledge application - use your knowledge to answer questions about the types of celestial object trajectories

Additional Learning

To learn more about the trajectories of celestial objects, review the accompanying lesson called The Four Kinds of Trajectories for Celestial Objects. This lesson covers the following objectives:

  • Discuss the relationship between trajectories and conic sections
  • Describe the path the different trajectories take
  • Define conic section
