| 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.. | |
