Grok Takes E&M Physics Exam

Can AI (artificial intelligence) and/or ML (machine learning) help students learn introductory physics? We recognize that Grok, ChatGPT, and the like, have the potential to dramatically change the landscape in our introductory physics courses. Many of the introductory physics textbook publishers are now looking at how to incorporate AI/ML into their educational materials. How can we, as instructors, incorporate AI/ML into our physics courses?

As a followup to previous work, where ChatGPT 3.5 took a physics exam in the algebra-based course on mechanics, here we have Grok-1 taking an exam in the algebra-based E&M physics. How good is Grok? I discuss how it performed on the exam, compare its score to the rest of the class (humans), and discuss some of the differences in Grok versus ChatGPT (in terms of their exam abilities).
