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 Periodic Motion Video Tutorial explains what is meant when saying that an object is undergoing periodic motion. The meaning of period, amplitude and frequency are described. Numerous representations are used to convey a conceptual understanding of an object that vibrates about a fixed position in a regular and repeated fashion.
The video lesson answers the following questions:
What traits characterize an object that undergoes periodic motion?
How do the quantities period, frequency and amplitude describe an object undergoing periodic motion?
Physics Interactives: Vibrating Mass on a Spring
This interactive simulation allows you to explore the back-and-forth motion of a mass on a spring. Change the mass, the nature of the spring, and the amount of damping and observe the result. A few minutes with this sim will spring you forward in your understanding of vibrational motion.
The Calculator Pad: Vibrations and Waves: Problem Set WM1
The Calculator Pad features practice problems with immediate feedback and links to audio help and tutorial pages. In Problem Set WM1, you must use information about an object undergoing periodic motion in order to determine the frequency and/or the period of vibration. Great practice!

Physics Interactives: Vibrating Mass on a Spring
This interactive simulation allows you to explore the back-and-forth motion of a mass on a spring. Change the mass, the nature of the spring, and the amount of damping and observe the result. A few minutes with this sim will spring you forward in your understanding of vibrational motion. It is accompanied by a ready-to-use Activity Sheet.
Concept Builders: Vibrational Motion
We have a growing collection of Concept Builders in our Vibrational Motion chapter. While most pertain specifically to pendulum motion and the motion of a mass on a spring, you should be aware that they're their for coverage that is related to this video. It's good stuff. Check them out. Use them now or use them later.
Curriculum Corner : Wave Motion
We will admit ... it's a bit early for Waves. But if that's a topic that is coming up after vibrational motion, then you might wish to inspect what we have now in our Curriculum Corner section. This is free curriculum for the taking. And for a few extra bucks, you can obtain the source documents and purchase a license to place them and any deriviative from them on your course management pages.
Science Reasoning Center: Vibrations and Waves
Our Science Reasoning Center is the perfect place to find that activity that upgrades the level of critical thinking, data analysis, model-building, and careful reading. This is where Process is king and content is just the medium. Get students thinking and reasoning at the Science Reasoning Center. We have some activities on pendulum motion and vibrating masses on springs.
The Calculator Pad: Vibrations and Waves: Problem Set WM1
The Calculator Pad features practice problems with immediate feedback and links to audio help and tutorial pages. In Problem Set WM1, students use information about an object undergoing periodic motion in order to determine the frequency and/or the period of vibration. Great practice for this stage of the learning cycle!
