This HTML5 simulation demonstrates how friction affects temperature and molecular motion. Rub two books together to generate friction and watch the temperature increase as the molecules' kinetic energy increases. As greater friction is applied, some of the molecules in the "Chemistry" book break free of their bonds. However, the molecules in the "Physics" book are much more tightly bound. (No amount of heat will remove them.) This simulation is appropriate for conceptual physics courses as a way to introduce friction in terms of both macroscale and molecular-scale interactions. Teaching ideas and activities are included.

This is part of a larger collection developed by the Physics Education Technology project (PhET).

Next Generation Science Standards

Disciplinary Core Ideas (K-12)

Structure and Properties of Matter (PS1.A)
  • A stable molecule has less energy than the same set of atoms separated; one must provide at least this energy in order to take the molecule apart. (9-12)
Definitions of Energy (PS3.A)
  • Temperature is a measure of the average kinetic energy of particles of matter. The relationship between the temperature and the total energy of a system depends on the types, states, and amounts of matter present. (6-8)

Crosscutting Concepts (K-12)

Systems and System Models (K-12)
  • Models can be used to predict the behavior of a system, but these predictions have limited precision and reliability due to the assumptions and approximations inherent in models. (9-12)
  • Models (e.g., physical, mathematical, computer models) can be used to simulate systems and interactions—including energy, matter, and information flows—within and between systems at different scales. (9-12)

NGSS Science and Engineering Practices (K-12)

Asking Questions and Defining Problems (K-12)
  • Asking questions and defining problems in grades 9–12 builds from grades K–8 experiences and progresses to formulating, refining, and evaluating empirically testable questions and design problems using models and simulations. (9-12)
    • Ask questions that arise from examining models or a theory to clarify relationships. (9-12)
