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 Interactives Forces in 2D Equilibrium Notes

Equilibrium Notes

Notes:

The Equilibrium Interactive is an adjustable size file that displays nicely on just about any device - on smart phones, tablets such as the iPad, on Chromebooks, and on laptops and desktops. The compatibility with mobile phones, iPads, other tablets, and Chromebooks make it a perfect tool for use in a 1:1 classroom. Its dimensions can be adjusted to just about any dimension by dragging the lower-right corner of the iFrame.

Teaching Ideas and Suggestions:

This Interactive provides students with excellent practice analysing force vectors in two dimensions. There are five levels of difficulty. Students can elect to change difficulty levels after each problem. Every problem involves the same task - balancing the given force vectors by dragging out a force vector with the appropriate magnitude and direction. The five levels of difficulty differ from one another by the number of given force vectors that are provided. In the first and easiest level, students balance one force vector. In the fifth and most difficult level, students must add a force vector to balance five given force vectors.

All force vectors are displayed on a grid of squares with a magnitude of 1 unit along each edge. The x- and y-components of the force vector is displayed near the head of the vector. Students can analyze the components of the given force vectors to determine the required components of the equilibrant vector. Students will receive immediate feedback regarding thier answer. They will have an opportunity to try another problem with the same level of difficulty or to change levels to a higher or lower level of difficulty.

Progress for each of the levels is displayed in the form of the number of attempts and the number of correct solutions. The progress information is not saved.
