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 Mechanical Energy Conservation Video Tutorial explains what is meant by mechanical energy conservation and the conditions under which mechanical energy is conserved. Mechanical energy conservation is contrasted with situations in which energy is transferred across the boundary as a result of external forces doing work. Numerous examples, illustrations, and animations assist in the explanations.
The video lesson answers the following questions:
Under what conditions is mechanical energy conserved?
What is meant by saying that mechanical energy is conserved?
Concept Builders, Work and Energy section: Up and Down with Energy
Our Concept Builders provide great practice. Most are very incremental, beginning with the basic concept and building upward from there. This is a great example of that approach. Use mechanical energy conservation to analyze a projectile's motion.
Minds On Physics, Work and Energy Module. Missions WE7 and WE8
Minds On Physics is a unqiue set of questioning modules that present questions and provide immediate feedback to student response. When difficulty is detected, it continuously presents similar questions to target your difficulties. Each question is accompanied by a rather extensive discussion of how to approach the question. You want to learn? Devote some time to "MOPs".
Calculator Pad, Work and Energy Problem Set, Problems #15-18, #21
Our Calculator Pad section consists of a collection of problems on varied topics, Each problem comes with an answer and an audio file that extensively addresses the solution. What more do you need? If your course emphasizes problem-solving, then we would emphasize that you make the Calculator Pad your friend.
Teacher Toolkits, Work-Energy Relationships
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 Builders, Work and Energy section: Up and Down with Energy
This Concept Builder incrementally builds on the idea of energy conservation. Students begin determining values of KE and PE for the up-and-down motion of a ball. By the end of the exercise, they are calculated height and speed values based on the energy analysis.
Concept Builders, Work and Energy section: Energy Analysis 1
This Concept Builder will provide students with some awesome practice with the quantitative side of this topic. And if you hae a Task Tracker account, you can assign the task and know how students have done.
