Define internal energy as the total kinetic energy and potential energy of all particles in a system.

Define internal energy as the total kinetic energy and potential energy of all particles in a system. Practical lens: Link apparatus, readings, and uncertainty to the exact measurement named in the objective. In Internal energy, this means internal energy combines particle kinetic and potential energy. The answer should use the approved wording from Internal energy and energy transfers, include internal energy, kinetic energy, potential energy, system, and avoid drifting into another section of Particle model of matter. For revision, practise saying the exact objective aloud, then add the one calculation, particle movement, collision, graph, or practical detail that makes the statement true. A strong exam response for checkpoint 31 is specific to define internal energy as the total kinetic energy and potential energy of all particles in a system and does not reuse a generic explanation from a neighbouring objective.
