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 Physics of Work Video Tutorial explains the concept and mathematics of work. The definition of work the means of identifying work, the mathematical formula and associated unit for work, and the distinction between positive and negative work are emphasized.
The video lesson answers the following questions:
What is meant by work and how can you know if work is being done on an object?
What is the equation for work?
How are positive work and negative work distinguished from each other?
Work Concept Builder
There's nothing like a Concept Builder for quick checks of your understanding. This one on the topic of Work will test your understanding of examples and non-examples of work and the distinction between + and - work. Try the first two activities for a great check up.
Minds On Phyiscs - Mission WE1: Work
You want to raise your game a notch? Here's how: click this link and try the newly revised Minds On Physics mission on the topic of work. Your reward will be given on test day.
The Calculator Pad: Work and Energy Problem Set, Problems #1-4
Not all Physics courses are created equal. If yours emphasizes the solving of Physics word problems, then get acquainted with our Calculator Pad section. You will find problems with a wide range of difficulty level, answers to every problem, and an audio-guided solution. Check it out!
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.
Work Concept Builder
There's nothing like a Concept Builder for quick checks of student understanding. This one on the topic of Work will test student understanding of examples and non-examples of work and the distinction between + and - work. The first two activities provide a great follow up to this video.
Minds On Phyiscs - Mission WE1: Work
Our newly revised HTML5 version of Minds On Physics can provide your students the workout they need to be successful in Physics. Each question in these interactive questioning modules are accompanied by a question-specicific help page. Best of all, you can purchase an account and track your students' progress. For intense practice, you can't go wrong with "MOPs".
The Calculator Pad: Work and Energy Problem Set, Problems #1-4
If your course provides a moderate to heavy emphasis on the solving of Physics word problems, then the Calculator Pad should become your friend (and more importantly, your students' friend). Each chapter contains a set of problems with answers and an audio-guided solution. Send your students there to improve their problem-solving skills.
