Lesson 3: Microscopic Explanations & Thermal Dissipation
Duration of Days: 7
Lesson Objective
Students will be able to calculate the discrepancy between initial and final mechanical energy in an open system to determine the exact amount of energy dissipated by friction.
Students will be able to develop a particle-level model illustrating how macroscopic kinetic energy is converted into microscopic internal thermal energy (molecular vibrations) through friction.
Where does the "lost" energy go?
HS-PS3-2 Develop and use models to illustrate that energy at the macroscopic scale can be accounted for as a combination of energy associated with the motions of particles (objects) and energy associated with the relative position of particles (objects).
Connecting macroscopic energy to microscopic particle motion.
