About This Chapter
CEOE Physics: Laws of Gravitation - Chapter Summary
The engaging video lessons in this chapter can be viewed from any Internet-ready device, making study convenient for busy educators. As you work through the lessons in preparation for the CEOE Physics exam, you will review:
- The law of universal gravitation
- Centripetal force
- Gravitational attraction and potential energy
- Newton's laws of weight, gravity and mass
- Kepler's laws of planetary motion
- Orbital mechanics
Each lesson is accompanied by a short quiz that lets you practice using the material you've covered and pinpoint where additional review is needed. Video transcripts make it easy to locate key terms and review the concepts.
Objectives of the CEOE Physics: Laws of Gravitation Chapter
This chapter covers the laws of gravitation you'll likely encounter on the CEOE Physics test. Use the lesson quizzes to practice using the concepts and get accustomed to the formatting of the exam's questions.
You will be given four hours to complete the computer-based test, which includes eighty-one tasks. One item on the test is an extended-response essay worth fifteen percent of your score. The other tasks are multiple-choice questions accounting for the remaining eighty-five percent of your score, which will be available upon completion of the exam. A full report will be sent to you within two weeks of your test date.
1. The Law of Universal Gravitation: Definition, Importance & Examples
Gravity is what pulls us toward Earth, but it's also what pulls Earth toward us. This is explained by the law of universal gravitation, which describes how all objects in the universe have this important force between them.
2. Centripetal Force: Definition, Formula & Examples
When an object is traveling in a circular path, centripetal force is what keeps it fixed in that path. Learn more about this force, how it is calculated and examples of its occurrence. A quiz is provided to test your learning.
3. Gravitational Attraction of Extended Bodies
After watching this lesson, you will be able to explain what an extended body is, understand the derivation for the force of gravity between a point charge and a long, thin bar and solve problems using the result of that derivation.
4. Gravitational Potential Energy: Definition, Formula & Examples
In this lesson, you will learn what gravitational potential is, the equation we use to calculate it, and how to use that equation. We'll look at some real-life examples so you can see how it works. A short quiz will follow.
5. Newton's Laws and Weight, Mass & Gravity
Did you know that mass and weight are not the same? This lesson describes the difference between the two as well as the effect of gravity on weight. Examples are used to teach you how to calculate weight based on mass and acceleration of gravity.
6. Kepler's Three Laws of Planetary Motion
Find out about the interesting life and major contributions of Johannes Kepler. This lesson will also teach you how to find out how long it takes a planet to revolve around the sun!
7. 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.
8. Eccentricity & Orbits of Planets
After watching this lesson, you should be able to explain what eccentricity is and calculate the eccentricity of an orbit given relevant distance measurements. A short quiz will follow.
