was thre an old man how told you that
** ENERGY IS MASS IN MOTION!!** ??!!
in micro and macrocosm !!!
(his name is Y.Porat )
-------------------------
--------------------------
work is done by energy !!
energy is more abstract
work i s more specific for specific cases !!
-----

see above

---------------------------------
at speed of light you still dont know what is the work that
CAN BE DONE !!! for a specific case
you have to know what is the mass that is moving there
b
how much of it will be materialized in c csse of splinting the
energy to a few directions in specific cases
(while its mass will collide to a few directions (vectors )

its tme for you to learn that
massis conserved as energy is conserved !!
see my thread:
'Mass id conserved BECAUSE energy is conserved !!!""
(both mass AND ENERGY ARE CONSERVED !!
iow
there is nor relativistic mass !!!
mass is not growing with speed!!
IT IS THE ENERGY NEEDED TO ADD MORE VELOCITY THATIS GROWING !!
it is not
F = gamma m a
but
F/Gamma = m a
AND m RETAINS CONSTANT !!
so
quite the opposite to your above say :
it becomes more and more difficult to add more velocity
in orded to ad more velocity to mass !!!
the trouble with you young guys that you was born to
authenticate cars
in my old days
if your battery went off
we had to push out cars in order to ignite (tart ) it !!
and had you done it with your bare hands (and bones (:-))
you would understand BY HAND EXPERIENCE.)
THAT IT BECOMES TOAD MORE AND MORE ENERGY
TO ADD THE CAR MORE VELOCITY -
THE ENRGY INVESTED IF NOT ONLY THE FORE YOU NEED
BUT THE LONGER WAY YOU NEED TO RUN WITH YOUR FORCE
IN ORDER OF NOT LOOSING CONTACT WITH THE CAR !!!
i hop my above example is very meaningful and educative
keeping in mind that
**FORCE AGENTS** **THEMSELVES** HAS AN &&UPPER LIMIT OF VELOCITY
**--
TO RUN AFTER THEIR DRIVEN OBJECT (MASS)!!
---------------
BTW
i would omit the sci.philosophy !!
it is not philosophy it is handwork and experiment work (:-)
