comment How's the energy of particle collisions calculated?
OK. You have E = gamma m0 c2 so if you have the speed you have gamma and the energy. So yes, the energy will be higher. Note that in all these cases, when work with these concepts it is very rare to think in term of speed; it is easier to talk (and measure) energies and momenta.

comment A force's magnitude
You already know the answer ...; I was saying that a force is just a normal vector, call it magnitude, strength, length, norm, size, whatever you like. The magnitude (strength) is not different from "vector" as Herb said. A vector has a direction and a magnitude (strength).

comment What new breakthrough energy technologies are close to being realized?
I don't think anyone ever talked about anti-matter annihilation except Dan Brown. + this is not a real question as no one can answer it. I would vote to close.

No, because you won't be able to accelerate it to higher energy, because this other particle is heavier and then if you accelerate it with say the LHC, you would need a higher magnetic field, which you don't have.

The reasoning to have the speed of the protons at such high energy is similar to that case: physics.stackexchange.com/questions/139/speed-of-neutrinos/… . Basically: E/E0 = gamma =~ 3500 and gamma = 1 / sqrt(1- (v/c)^2) , you can then extract v (should be 0.some9s * c ).

comment Law for tap water temperature
In any case this model, as a model could still be valid; you have an exchange coefficient and a delta T .

@Herb: As you said, to consider the transient solution, we need a model for the tube and the surrounding environment.

@j.c. I like your slogan !

@j.c. OK, I agree with that.

comment Book about classical mechanics
I find it hard to read, I was looking for something intermediate that would allow me to benefit from Arnold's book more easily.

While answering this question I realized that it was not a real, not argumentative question... You should change the question as @j.c. suggested.
