Internal Energy of a System - GCSE Physics

🦊 In this GCSE Physics video, we describe the internal energy of a system as the total kinetic and potential energy of its molecules, modeling them as balls connected by springs representing intermolecular bonds. It explains that while both kinetic and potential energy contribute to internal energy, kinetic energy generally has a greater impact due to its larger magnitude. Additionally, the video outlines how the state of matter affects internal energy: solids have low kinetic and high potential energy, liquids have medium levels of both, and gases have high kinetic energy and low potential energy, resulting in varying internal energy levels across these states.
