The Equation For Angular Acceleration.

 V=(2πR/T)/(d/dt)Iv.

Although I suspect the Kabuki Princess wouldn't even be able to follow the example. 

Of a Gold Medal winning Figure-Skater pulling her arms in to increase the speed of her spin on her axis.

Technically it's;

√(V2/x+V2/y) > μ+w=t^μma^g.

When the Angular Acceleration on a curved track exceeds the Traction exerted on the Object by the track.

Gravity wins.

While that's just your common-or-garden Ballistic Projectile.

Tanϴ=v²/gR.

I'm not sure that 'Advanced Chemistry ' equations expressed as Ani DiFranco songs was a particularly useful tangent.

But at least I enjoyed myself.
