Agreed
You’re just saying that cause she’s hot
Perhaps.
I doubt I'll ever know.
Ok put the weight on a balloon with a small hole in it that I can over come buy blowing air into it keeping it afloat. In any of those cases work is keeping the weight afloat such that if the force that was holding it up was removed it would fall.
The table in your example is just an extension of the earth doing nothing even closely resembling work. The point I was trying to make is Physicist denie any work is taking place when two magnets oppose each other, I think there is and no I can't prove it, but Galileo couldn’t prove his theory either until the telescope was invented.
We are just waiting for another tool that I likely will never see but the new super magnets make trying to find that tool an interesting quest.
Your mind is ripe for being taken by perpetual motion scams.
No work is done on the balcony. Work is done moving the air.
Remove the table and the rocker will fall.
“The point I was trying to make is Physicist denie any work is taking place when two magnets oppose each other, I think there is and no I can’t prove it,”
Perhaps you should take a course if physics.
The PERSON in your example is just an extension of the earth doing nothing even closely resembling work.
Strangely if he quits blowing the weight is no longer floating, so I have to disagree.
If I replace on permanent magnet in this story with an electro magnet it immediately becomes a work operation because it only floats the 1 lb weight as long as the electric is on. Clearly the electric is the energy expended in the electro magnet/magnet trick. What is the energy expended in the PM/PM portions of the experiment since none is present then I guess nothing. In the blowing on the balloon obviously the only energy present is provided by the person doing the blowing. Take his energy out of the equation and the weight falls.
I thin any k6 science class could make these observations except the PM magnets because we have never attempted to definitely define the energy derived from the magnet.
Not necessarily
The greatest barrier to the truth is to believe we already have it. I am not buying into any thing that purports to be perpetual energy even if it was demonstrated to reputable scientists that agreed it was true.
It would take operable stations able to power a city with absolutely no connection to the outside world, for me to believe it.
We have a definition for perpetual but we have absolutely no idea what perpetual is.
“I thin any k6 science class “
I guess I should throw away my seven years of college majoring in engineering and go ask my grand-daughter which one of is right.
Please. Go take a physics course or at least stay in a Holiday Inn.
“Not necessarily”
Absolutely.
“The greatest barrier to the truth is to believe we already have it. I am not buying into any thing that purports to be perpetual energy even if it was demonstrated to reputable scientists that agreed it was true.”
What you are bubbling about is a perpetual motion machine.
“Strangely if he quits blowing the weight is no longer floating, so I have to disagree.”
Blow against the side of your house with the same force. The wall does not move. How much work are you doing to the wall?
ZIP. Nada.
Exactly the same amount of energy is bring expended it just isn't accomplishing anything sort of like this discussion.
“Exactly the same amount of energy is bring expended it just isn’t accomplishing anything sort of like this discussion. “
In both cases the object doesn’t move. You have done no work on the object.
