Physics of Everyday Magic
📋 What it is
Balancing tricks, inertia stunts, and “floating” objects are physics laws in disguise.
🗣️ Coach says
The classic “pull the tablecloth without moving the dishes” is inertia: objects resist changing motion. A balancing toy works because of its centre of mass. What looks like a magician’s secret is really a physics law you can name — and once you name it, the magic makes sense.
🧠 Memory hook
Magic tricks are physics laws in costume — inertia, centre of mass, forces.
😂 Giggle
Why was the light ray such a great performer?
It always knew how to reflect on its act!
😲 Whoa!
The tablecloth trick works because the dishes’ inertia keeps them still if you pull fast enough — the cloth slides out before friction can drag them along.
✅ Quick check: Why do the dishes stay put when a tablecloth is yanked fast?
Say your answer out loud first — then reveal.
Inertia — objects resist changes in motion, so a quick pull slides the cloth out before the dishes can move.
Inertia keeps still objects still unless a force acts long enough.
🧪 Try it! (2 minutes)
Put a card on a cup with a coin on top. Flick the card fast — the coin drops into the cup (inertia).
