About This Chapter
Gravitation Principles - Chapter Summary
While going through these lessons, you'll deepen your understanding of gravitation principles. Some of the topics covered include the law of universal gravitation, escape velocity, and use of formulas to calculate gravitational potential. You'll also learn about the life and contributions of Johannes Kepler. After reviewing the lessons, you should be ready to:
- Explain Kepler's three laws of planetary motion
- Define and explain the importance of the law of universal gravitation
- Provide an example of the acceleration of gravity
- Calculate gravitational potential energy
- Explain the concepts of circular velocity and escape velocity
- Explore the difference between artificial and natural satellites
As you review the short lessons, you should find the material easy to grasp. If necessary, you can use the 'Help' feature to submit questions to instructors. Video timelines let you guide the learning process and review only the topics you need to review. A brief quiz is available for each lesson to test your knowledge.
1. 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!
2. 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.
3. The Acceleration of Gravity: Definition & Formula
In this lesson, we will introduce the acceleration due to gravity. Objects in free fall are one of the few real world examples of straight line motion with constant acceleration, so they are commonly used when learning kinematics.
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. Calculating Gravitational Potential Energy
An object can have gravitational potential energy due to its location in a gravitational field. In this lesson, learn how to calculate the gravitational potential energy of objects in different situations.
6. Circular Velocity & Escape Velocity
This lesson will describe the concepts of circular velocity, escape velocity, open orbits, closed orbits, and geosynchronous satellites. It will provide the equations necessary for you to be able to calculate out circular and escape velocity as well.
7. Satellite: Definition & Uses
In this lesson, you will learn what a satellite is, the distinction between natural and artificial satellites, and some of their practical uses. A short quiz will follow.
