Energy and momentum.The misunderstanding has prevailed
Two train wagons of the same mass will impact.
Wagon A has velocity 10 and wagon B 0.When they impact a lock will make them conjoint.
Which will be the velocity of two wagons and which the energy after the collision;
We use the conservation of momentum (...not the energy)and we will find
that the velocity will be 5.We note that we have a loss of KE. AND we say with endless silliness and easiness that kinetic energy transformed to heat (and sound) the simple logic obey me to ask: <<<<<How the particles of the wagons have heat without momentum? Since all the momentum is visible to us, as velocity of the wagons.>>>>>>
All we know that must eventuate to the conservation of two quantums K.E. and P (for the most is only equations because of misunderstanding of the real meaning)
Type at google:{ James a Putnam Momentum and Energy} you will find a very helpfull article.
I think that few know their nescience , fewer know it, but can not do anything to learn ( ineffectual searching on books ,web).The people who know is the rarest.
I want to know the fundamental of physics like a scientist and no like accountant who has memorized the methods of solving problems and finish them automatically and ignores what the represent
Despite the previous i have a thought of the "two wagons" in the case of pendulum and bullet...
-We have answer of relativity that energy represents the matter.
-In 19th century scientists had disagreement of which of two quantums represent the element of difficulty to change velocity(see halliday and resnick book).Note that force is not the ordinary word ,people use ,it is a mathematical variable.Also they had engrossment how the same force to same object need different energy supplys depend of its different previous velocity.
If you have understand the collision of different mass object "in action-reaction level" the meaning of energy in classical mechanics
I please you to reply me or send me the adresses of the answers.Thanks of reading.Sorry if i have done language mistakes.
