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 this link to contact us .

Momentum and Its Conservation


Photos from The Physics Classroom's Flickr Group

Lesson 1: The Impulse-Momentum Change Theorem

Lesson 1 discusses the concept of momentum and the loss and gain of it in situations in which impulses are experienced. Items in the group's pool include strobe photos of bullets piercing water balloons, grapes and egss, photos of athletes (pitchers and batters in baseball, tennis players, ping pong players, boxers), meteor craters, bumper cars, and martial arts experts, and much more. Photos complement many of the discussions from Lesson 1 of the Momentum and Its Conservation chapter of The Physics Classroom Tutorial.

Lesson 2: The Law of Momentum Conservation

Lesson 2 discusses the application of Newton's laws to the analysis of collisions. The law of conservation of momentum in an isolated system is explained and used to analyze collisions. Items in the group's pool include objects and phenomena such as Newton's cradle, water balloon popping, strobed water drops, air puck collisions, billiards, rockets, boxers, and much more. Photos complement many of the discussions from Lesson 2 of the Momentum and Its Conservation chapter of The Physics Classroom Tutorial.
