what can we take away from this experiment in torque chasing
momentum?

Physics is fun.
I like to remind myself of the 1st and 2nd law of Physics often.
What are your thoughts on this experiment in the video?

well..it immediately was a reminder of a few toys, i had when
i was kid the gyroscope.
i was intrigued in what happens with so much momentum an force
in this experiment ..thus your reference into what i
thought...was how was i to stop my little DC permanent magnet
motor an get it started, once i had it in motion... and how it
was going to take torque an momentum to generate energy... as i
said it is very small motor fits in the palm of my hand.. i
believe i can gain with momentum /more speed.. an angular
directional force..it would seem it is going to amplifying my
torque too!an now i may be able to control it or stop it...also
have you ever see the inside of a wind up clock it take stored
energy under tension! if that makes any sense.....
how i could apply it in principle? i ask my self(change my
design >maybe! to allow more inertia to increase momentum for
more rpm an torque chasing it!.. i'm not very efficient with
the high 2600 RPM that is for sure.. .. what would be ideal is
less torque, lower RPM more energy output.. i need to
generate at a lower speed for higher voltage with less torque
yes if it was a large motor i would need more torque ......so i
need to reverse engineer the motor to get less rpm an more
energy ? an apply this theory some how, but how do i get more
RPM? (threw momentum)? he had a his speed grinder rotating his
wheel creating inertia
thus back to my conclusion from the observation.... an it was
just that an observation, we have opposing angular motions
agreed...(in different directions opposing forces) as
explained... but when he added the weight to the equation..[ it
caused another law in physics (GRAVITY)] an inertia effect
.....to increase torque! but it also reversed slowed momentum,
he immediately after a few moments showing .. torque increased
chasing momentum........ threw it out of harmonic balance
...with a 3rd opposing force ....gravity.what i thought was just
a balance an gravity phenomena from the weight .... but not so
he influenced another law ...which came into equation/as an
effect....gravity thus causing ....friction an loss of
speed/power slowing momentum....there must be a force to
continue to propel an keep all 3 in harmony , i still believe
you could use the weight applied in the equation in one of the
directions by increasing momentum threw a different application
....the aerodynamics of a propeller ... an a force driving it...
must be in the equation a transfer of momentum..
the weight : causing 3 mechanical effects friction (a breaking
system, slowing momentum, threw gravity and an increase in
torque chasing momentum with gravity ) short term inertia
increases in less torque... thus you need a constant force to
propel momentum) ? ...still thinking! about it.. i had to
re-write my answer after i came back from he doctor an thought
about it some more..just now proof read an corrected my
statement on my return from the doctor..
