Physics Classroom is making strides to make our site accessible to
everyone, and features many accessibility features.
Our site contains 6 navigation areas. The Primary, Secondary,
and Page Level navigations have a screen reader version of their nav
structure that allows using the left and right keys to navigate sibling
navigation items, and up or down keys to navigate parent or child
navigation items. The others can be navigated using tabs.
Within the main content, we leverage headers to provide in page or
in tool navigation.
Although we are still rebuilding our content to leverage these tools,
our images should have both short and verbose descriptions, the later
describing in great detail the image for those who cannot see. Any
formulas found within the images are often in the image figure below the image.
Equations and formulas are rendered using MathJax, which has both verbal,
braille (including nemath braille), and keyboard navigation within them.
Learn how to configure and leverage this for various screen readers on our
Equation Navigation Page.
While not every area of
Physics Classroom is usable purely from keyboard and screen reader, we
are committed to continue work on making this possible. If you have
questions or need additional help, please use

The Non-Mechanical Energy Video Tutorial explains what non-mechanical energy is and how it is different than mechanical energy. Five non-mechanical energy forms are described and examples are given of each. The emphasis of the video is on developing the skill of keeping track of energy.
The video lesson answers the following questions:
What is meant by non-mechanical energy?
What are examples of non-mechanical energy?
How can you keep track of mechanical and non-mechanical forms of energy?
Concept Builder, Work and Energy Section: Work
In this Concept Builder, you will learn to identify whether positive, negative, or zero work is being done, to identify the force that is doing the work, and to describe the energy transformation associated with such work. It's this third activity that is most associated with this video.
Physics Tutorial - Work, Energy, and Power Chapter
When you need to brush up on any topic, we recommend a trip to the Physics Classroom Tutorial. Its easy-to-understand language combined with informative graphics and appeals to your sense of reason make this a powerful learning tool.
Teacher Resources
Curriculum Corner, Work, Energy, and Power Section: Energy
Get students active and thinking with one of our free Think Sheets from the Curriclum Corner section of our website. You may not find one that is perfect for this vide ... but you're likely to find several that have relevance to your current unit.
Teacher Toolkits, Work-Energy Fundamentals
Try a Teacher Toolkit ... you might be very glad that you did. Each toolkit includes annotated links to vetted resources from across the web that we feel reliably support the specific topic. Give this one on work and energy a try.
Concept Builder, Work and Energy Section: Work
In this Concept Builder, students will learn to identify whether positive, negative, or zero work is being done, to identify the force that is doing the work, and to describe the energy transformation associated with such work. It's this third activity that is most closely associated with this video.
Physics Tutorial - Work, Energy, and Power Chapter
Our Tutorial section is the textbook on the site. Its also the most trafficked section of the site. And for good reason. It proves time and again that anyone can understand Physics. Point troubled students to this page. Point all your students to this page.
