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.

Getting the Hang of Charge - Directions

Using the Getting the Hang of Charge Concept Builder is quite simple. You will be presented with a description of the interaction between two or more balloons ... and on occasion between one of the balloons and some neutral bits of paper. In all cases, the charge of Balloon A is stated and you will have to use the information about the interaction between the balloons (and between a balloon and paper bits) in order to determine the charge on either Balloon B or Balloon C. Use the rules that oppositely-charged objects attract each other, like-charged objects repel each other, and a neutral and a charged object attract each other to determine this unknown charge. You can answer the question by tapping on the buttons labeled Positive, Negative, and Neutral that are displayed near the bottom of the Concept Builder. You can tap on more than one answer since the given information may not be sufficient to isolate a single answer from among the three answer options. Tapping once on a button selects that answer. Tapping a second time deselects that answer. You will know an answer is selected because the text turns red (from grey) and the button is highlight with a yellow highlight. Each tap of the button results in the creation of a verbal statement of what answers you have currently selected. You will see this in red text just above the buttons. Whenever you have at least one answer selected, a Check Answer button will appear. If you are satisfied with your answers, tap on the Check Answer button. Your answers will be evaluated and your Progress Report will be updated.

Your goal is to earn "Stars" and to complete one or more levels of difficulty. Stars are earned when you show success on a particular question. Once you show success on all the questions at a particular difficulty level, you will earn the reward for that level.
