Describe limitations of simple particle model diagrams for representing real particles, forces and motion.

Describe limitations of simple particle model diagrams for representing real particles, forces and motion. Unit lens: Check the units before giving the final statement so the physics quantity is not swapped. In Changes of state, this means the particle model explains the observable property using particles. The answer should use the approved wording from Changes of state and the particle model, include particle model, 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 30 is specific to describe limitations of simple particle model diagrams for representing real particles, forces and motion and does not reuse a generic explanation from a neighbouring objective.
