My instructor continuously insists on the idea that I don't understand/believe. Therefore I hope the people here could verify/discuss with me.
Regarding the conservation of mass-energy, he took an example of the head-on-head collision of two identical clay lumps with same speed. What he asserted was that all the kinetic energy of two lumps will be converted into mass, in which the same element will be produced. If two lumps are not identical, then different elements will be produced according to the the ratio of the ingredients of the two lumps.
Also, same idea applies to the work done on a spring. The energy (work) is converted to the increase in mass of the spring. In addition, the increase in potential energy is just the increase in the mass of the object. Conclusively, there is no other forms of energy besides mass and kinectic energy. (He rahter insists that the kinetic energy is not the energy related to the increase in mass.)
Q:
Should all these be true, then what is the meaning of the rest mass of any elementary particle if it all depends on all sorts of the energy associated to those particles? (Gravitational potential energy, for example)
And, does it imply the mass is not intrinsic property of a particle?
That is to say, electron will be heavier after a collision?
When mass is produced, what if the expected delta mass cannot be divided by the mass of the expected elemetary particle?
Can anyone clarify a little bit for me? I somehow cannot understand how nature knows what mass to produce and according to what ratio. Why we all force ourselves to believe that all kinds of energy are nothing but increase in mass without any mechanism or rationale?
Thanks a lot for the time spent on my question in advance!
I'm really stuck at this point.
