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 Work and Energy Stepping Up to PE and KE

Stepping Up to PE and KE

The Stepping Up to PE and KE Concept Builder relies on the use of a staircase model to help learners to relate the potential energy of an object to the height of the object. Learners will also relate the change in potential energy of a falling object to the change in kinetic energy. There are three difficulty levels, with each level adding an extra component of difficulty ... and an extra blank to determine. A built-in number pad makes numerical entry very easy on mobile devices. Feedback is immediate and communicated by means of a color code system. Learners can repeat a difficulty level in an effort to improve their health percentage. Help is provided for each difficulty level. Use of this Concept Builder with our Task Tracker system allows teachers to track student progress.

Users are encouraged to open the Concept Builder and begin. There is no need for an activity sheet for this Concept Builder.

Learners and Instructors may also be interested in viewing the accompanying Notes page. Technical information, teaching suggestions, and related resources that complement this Interactive are provided on the View Notes.
