What's NEW at The Physics Classroom?

We've been at this task of providing students, teachers, and classrooms high-quality, ready-to-use resources for a long time. And we are as passionate about it now as we were 25 years ago when we started. We are always working on something new. But it is such a big website that the new additions often get nested deep inside of a section and are never noticed for months or even years after being published. So we're aiming to fix that problem with this page of announcements. Visit this page to find out about our most recent additions. And check back often in anticipation of finding new surprises.

Forces in Two Dimensions Concept Builders

Fixed! Finally fixed! A couple of our Forces in 2D Concept Builders have had a shaky history of integrating with Task Tracker, most notably Solve It! Vectors and Newton's Second Law and Solve It! Inclined Planes. The Concept Builder worked great but Task Tracker teachers who used them likely noticed that their ability to track was suspect. That is no longer the case. We have found the bug and it is exterminated. Enjoy these CBs Task Tracker users!
