That's why the total energy bar stayed the same height the whole time.\" **\n\nWHAT WE SAW (energy bar chart in the sim):\n- At the top: all potential energy (PE), zero kinetic energy (KE). Speed = 0.\n- At the bottom: all kinetic energy, PE at its lowest. Fastest speed.\n- Going back up the other side: KE turns back into PE.\n- She reached the SAME height on the right side as where she started, never higher.\n- Total energy bar: never changed.\n\nEquations (NOT for this explanation, it's a \"words only\" lab question): PE = mgh, KE = ½mv²\n\nLab question: \"In words, explain why the skater never goes higher than her starting point.\"\nMy confusion: why can't she go higher if she's going really fast at the bottom?\n\nLab report due Monday.","rules":[{"type":"numberedItems","count":3},{"type":"maxWords","max":80},{"type":"plainText"}],"mistakes":[{"title":"Asking the general question","why":"The AI explains with equations and roller coaster examples, not your sim.","fix":"Say: \"Use only the skate park sim from my lab.\"","checks":["r0"]},{"title":"Not saying how many sentences","why":"The AI picks its own number, and it usually picks more sentences than you need.","fix":"Be exact: \"Exactly 3 numbered sentences.\"","checks":["numberedItems"]},{"title":"Missing the correction","why":"Your notes say friction was on at first, which would change the explanation.","fix":"Add: \"Friction was off, per Mr. Kimura.\"","checks":["r1"]},{"title":"No way to test yourself","why":"The AI explains and stops, so you never check whether it stuck.","fix":"Add: \"End with one line starting 'Check:' with a question, no answer.\"","checks":["r2"]},{"title":"Trusting the AI to count words","why":"AI is bad at counting.
