We investigated students' use of Newton's II law in mechanics and electricity and magnetism contexts.  We interviewed 16 students in a two-semester calculus-based physics course.  We found students' answers are consistent with two principal mental models and a combination of these two.  We explore whether the students who use Newton's Second Law in mechanics contexts continue to do so in electricity and magnetism.
