Yes much happier thank you, perhaps it would be better to say that an
electric motor has the same amount of torque available regardless of RPM?
Yes torque is the thing that breaks your wrist as you hold onto that big
drill with one hand, actually I remember back in the day these small
drills with big kick ass motors in the them and no secondary handle
where popular, not sure if any here remember them, they where solid
metal and had a big loop type handle on the back. We used to put a metal
bar through this loop to act as a secondary handle.
Whereas horse power is the thing that keeps the drill spinning until it
winds the power cord tight enough around itself to break it.
See no need for the fancy formulas that you could not have gotten from
education.

needs more

0.00001 rpm then if that makes you happier.
As I recall from physics back when, torque= I * [alpha] where I is the
angular/rotational inertia and alpha is the angular acceleration,
sorta like F=mA. Neither say anything about actual motion. You can
have a force F without any motion, e.g., gravity acting on a mass
(unless of course you are on the wrong side of the planet in which
case you might fall off).
Perhaps some physicists might want to weigh in
