The first law of thermodynamics states that doing work on an otherwise isolated system will cause its energy to change. Student performance in introductory mechanics on pretest and post-test questions suggests that traditional instruction is insufficient to develop a functional understanding of this principle. At the University of Washington, the Physics Education Group has been developing research-based materials1 on these topics. We will discuss common student difficulties in applying the relationship between work and energy, and implications these have for instruction on energy conservation.
