Demonstrate understanding of a physical system using energy concepts
This standard asks you to show that you understand how energy works in real-world situations, like falling objects, electrical circuits, or heating. You'll describe what's happening physically, explain what energy changes are occurring and why, and work with calculations or diagrams to demonstrate your knowledge. It's about connecting the dots between what you observe and the energy concepts behind it.
You can identify the energy equation needed, plug in some numbers correctly, and describe basic energy changes (like 'energy is lost').
You show complete working for multi-step calculations with correct units, explain *why* energy is lost or transferred (naming things like friction or air resistance), and link energy concepts to the actual scenario.
You handle complex calculations using multiple formulas with correct units, explain exactly where thermal energy comes from and link this to particle motion, and structure your answer with precise terminology showing real depth of understanding.
