# Ch 1: Circular Motion & Gravitation

Reinforce your understanding of circular motion and gravitation using the short, simple lessons in this chapter. These lessons and related quizzes can be used as a supplement to class materials or to help you prepare for exams.

## Circular Motion and Gravitation - Chapter Summary

What is centripetal force? Angular velocity? Gravitational field? These are the types of questions you can expect to explore in this chapter. You'll look at formulas used to calculate acceleration, speed and velocity, as well as equations used to solve problems involving uniform circular motion. Once you're finished with this chapter, you should be able to:

• Calculate speed and velocity
• Understand three formulas used to calculate angular velocity
• Define and calculate acceleration
• Explain Newton's law of gravitation
• Describe gravitational force and gravitational attraction of extended bodies
• Provide details about Cavendish's gravity experiment
• Discuss specifics about a gravitational field
• Create graphs for velocity and time of an object in motion
