Potential and Capacitance in Physics - Videos & Lessons In this chapter, you'll learn how an everyday item, like a battery, converts and stores electrical energy. Using easy-to-understand visuals, the instructor will explain the concept of electric potential, or how groups of tightly packed charged particles interact with each other to do work. You'll also find out how voltage is used to measure electric potential and how much work is accomplished by charged particles in an electrical circuit. Through the videos on capacitance, you can learn about the different types of electrical components that can store an electrical charge. Ohm's Law will be discussed, including the relationship shared by electrical current, resistance and voltage. When you've finished with the chapter, you should understand:

Lawrence Hall of Science - 24/7 Science How fast does the wind blow? What makes things sticky? Where do insects live and plants grow? What is the best way to clean up the environment? How do humans measure up in the animal kingdom? So many questions—and so many ways to find answers! Free Sound Effects SoundBible.com has thousands of free sound effects for everyone.

Speed & Stopping Distance of a Roller-Coaster - Physics - University of Wisconsin-Green Bay In this problem, you are first asked to find a speed of a roller-coaster when you are given information about how its height changes. If non-conservative forces are either known or small and if energy is converted from one form to another between the locations, then any time you relate speed and position of an object at two different points conservation of energy is the most direct way to understand the problem. In this case, you start out with stored gravitational potential energy and convert part of that energy to kinetic energy. In the second part of this problem, you are asked to find stopping force given stopping distance.

Astronomy Lesson Science and Islam: Astronomy Lesson (Science) The Astronomy lessons provide an introduction to the place of astronomy in Medieval Islamic scholarship and Islamic instruments in the Museum’s collection of historical interest. The second lesson is best combined with a visit to the Museum and is an introduction to the astrolabe and its use for astronomical and other practical purposes.

Welcome to Northrop Grumman Foundation's STEM Flix STEM Flix™ is a new, interactive video series provided for your viewing pleasure by the Northrop Grumman Foundation and Science Bob. And they are all about having fun with STEM – that is, SCIENCE TECHNOLOGY ENGINEERING and MATHEMATICS. With help from Boston science teacher and frequent TV guest, Science Bob, you will learn about these topics through videos that include experiments you can do at home, as well as some crazy demonstrations that show just how STEM works. Because when you think about it, STEM makes nearly everything we enjoy in our daily lives possible – from the circuits that make computer tablets work, to the materials used to make snowboards that allow you to do cool tricks! And what about some of things that you’d LIKE to do one day, like travel through time?! Well, while you might not be able to click your heels and end up back in the land of the dinosaurs just yet, the technology to make it possible may be closer than you think – all thanks to STEM!
