few general formulas

[lancaIV]

nothing  in the example is (velocity) accelerating,neither vertical nor horizontal or diametral !


Staying in constant velocity !

[nix85]

irrelevant, going up is WORKing against gravity and vice versa

[lancaIV]

that is equivalent of pushing a book across a table and then
pushing it back to exactly same place
as far as book's position is concerned overall work is 0
but work has been done, ur energy has been wasted,
that is, converted

irrelevant the process ,total physical effect       W = 0


pushing forward,pushing backward : linear/rotative device !?  Nearly-,Net-, Zero Energy     future program

[nix85]

what you speak is nonsense
again take the book example
you push it across the table
then back to original place
you claim no work is done
that is plain wrong

In the DDR. there was a job creation program:


In a warehouse, the same types of screws were brought together from a pile of screws by a work group,
these were brought together again in a second warehouse and brought back to the "work"- group as a mixed pile!


A.-B.-M.  : Arbeits-Beschaffung-Program,sozialistische Definition




"pointless/stupid work" and " Work: Physics,scientifical defintion"


by Physics : the above worker work value = Zero worth




In real ECONOMY the Zero-result :

The above proof relates to an exchange economy, but can easily be generalized to production economies. It is important that Walras' law does not presuppose an equilibrium in the individual markets, but also applies in imbalances. If there is an equilibrium on each individual market, which certainly does not occur in reality, the statement is trivial because a sum of zeros results in zero.
