47–49p. Abstract: “Perpetual motion” is a hypothetical type of motion that continues forever without any external energy input contributing to the system. Students should know that this is generally impossible because of energy losses due to friction or other nonconservative forces, or because some assumption has been made that violates the first or second law of thermodynamics (or both). The first law states that the total energy of an isolated system remains constant over time, and one of the most common formulations of the second law states that the entropy of an isolated system over time cannot decrease. ***______{For Hard Copy, Please visit Library.}________*** Electromagnetism| Newtonian mechanics| Magnetic materials 0031-921X https://doi.org/10.1119/5.0102604 https://doi.org/10.1119/5.0102604 240508 20240508082435.0
