Misconceptions & Reasoning
📋 What it is
Common myths: heavier things fall faster, energy gets “used up”, and cold “flows into” things.
🗣️ Coach says
Physical science has sticky myths. Ignoring air, a heavy and a light object fall at the SAME rate. Energy isn’t “used up” — it transforms and spreads out. And cold doesn’t flow in; HEAT flows OUT (cold is just less heat). A careful thinker checks intuition against evidence.
🧠 Memory hook
Same fall rate (no air). Energy transforms, never vanishes. Heat flows out, not cold in.

Why did the experiment fail in a vacuum?
It just couldn't catch its breath!
😲 Whoa!
Astronauts on the Moon dropped a hammer and a feather together — with no air, they hit the ground at the exact same time.
✅ Quick check: Ignoring air, does a heavy rock fall faster than a light pebble?
Say your answer out loud first — then reveal.
No — without air resistance, all objects fall at the same rate regardless of weight.
Gravity accelerates all masses equally; only air resistance changes it.
🧪 Try it! (2 minutes)
Drop a coin and a small crumpled ball of paper together. Nearly the same — the myth that heavy falls faster is about air, not weight.
