Physics Classroom is making strides to make our site accessible to everyone. 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. The Primary Navigation handles the first 2 levels of site pages. The Secondary (which is not always available) handles the 3rd and 4th level of structure. The Page level navigation allows you to navigate the current page's headings quickly. The Header Navigation contains the Light/Dark Mode toggle, Search, Notifications and account login. The Breadcrumb Navigation contains the breadcrumb of the current page. If the current page has a breadcrumb, you can get to it by skipping to the content and tabbing in reverse (shift plus tab). The Footer Navigation contains links such as Privacy, Contact, about and terms. Some resources contain an Audio Player that can be activated by holding down the T key for 3 seconds, and then using K to pause and resume. 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.

Home Concept Builders Vibrations and Waves Rocking the Boat

Rocking the Boat

The Rocking the Boat Concept Builder presents the learner with a problem about two boats anchored in a harbor and rocking up and down in the presence of waves that are entering the harbor. Given a description of the motion of the two boats, learners must determine the wavelength, frequency, period, amplitude, and speed of the water waves. There are 27 total questions that are organized into nine different Question Groups and spread across three difficulty levels. The three different levels of difficulty are distinguished from one another in terms of the number of problems and the degree of variation from one problem to the next. Use of this Concept Builder with our Task Tracker system allows teachers to track student progress.
