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 Newton's Laws Change of State Directions

Change of State - Directions

Using the Change of State Concept Builder is quite simple. You will be presented with a verbal description of an object's motion and the free-body diagram associated with that motion is shown - on the left, labeled Current State. You will be asked how the force diagram would change if the state of motion changed to a new state of motion. That new state is described in words and you will have to select the free-body diagram associated with that change in the state of motion. The new free-body diagram can be selected from a choice of five options. These options can be viewed by tapping on the diagram on the right side of the screen, labeled New State. Continued tapping allows you to view all five options. You can cycle through the options more than once by tapping on the New State diagrams. Once you think you have found the free-body diagram that matches the new state of motion, tap on the Check Answer button. Your answer 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 situation. Once you show success on all the graphs at a particular difficulty level, you will earn the trophy for that level.
