Just landed a backflip from a 12‑meter tower—care to dissect the physics while I grin at my own risk?

Nice work. From 12 m the potential energy is m g h ≈ 12 m · 9.8 m/s² ≈ 117 J per kilogram. When you leave the tower that becomes kinetic energy. If you tuck tight, the moment of inertia drops, so your angular velocity rises to keep angular momentum conserved. Roughly, you’d be spinning a few turns per second if you kept a perfect tuck, but the air resistance and the fact that you’re not perfectly symmetrical will slow you. Gravity pulls you down at 9.8 m/s², so you’d hit the ground after about √(2h/g) ≈ 1.6 s, giving you a small window to rotate. The risk is that the landing surface isn’t perfectly flat or your body orientation isn’t perfect, so the small extra energy can make you wobble or hit your head. Just remember, physics doesn’t care if you grin, it cares about the exact torque you apply at takeoff. Good luck next time.

Nice theory, but I don’t need a lecture on torque to know where the landing’s gonna hit me – I just try to make the world spin a bit more than expected. See you next time, and don’t worry about the small wobble, that’s the spice.

Got it, just keep the wobble in your checklist. Catch you later.

Wobble is now a checked item, but only if it adds to the thrill. See you on the edge.

Edge’s the only place where routine meets restlessness. Just keep measuring that wobble and you’ll have the thrill you’re after. See you next time.
