Formula and units
ω = (2π/60)n; a = ω²r; F = ma; g multiple = a/9.80665; v = ωr. For each q, replace n with qn and keep mass and radius unchanged.
Scope
This ideal model describes a mass moving in a circle at constant radius. Use the radius to its centre of mass. The force is a magnitude: the real centripetal force is inward; centrifugal framing is outward in the rotating frame. 9.80665 m/s² is standard reference gravity, not measured local gravity. Inputs and q are finite and nonnegative; q above 1 is only an arithmetic scenario. Results outside the representable numeric range, including underflow or lost nonzero terms, are rejected. This does not establish rotor ratings, balancing, permissible overspeed or a safe operating range.

GOOD TO KNOW
Common questions
What does the gravity multiple mean?
It divides acceleration by the standard reference 9.80665 m/s². It is not a force and does not measure local gravity.
What happens at zero mass, radius or speed?
Zero mass gives zero force but can leave acceleration and speed nonzero. Zero radius gives zero acceleration, force and tangential speed; angular velocity can remain nonzero. Zero rpm gives zero for all five outputs.
Are factors above one safe?
The arithmetic accepts them, but it provides no equipment rating, balance assessment or overspeed permission.
