What is pure energy in matter-antimatter annihilation made of? I used to read the term "pure energy" in the context of matter-antimatter annihilation Is the "pure energy" spoken of photons? Is it some form of heat? Some kind of particles with mass? Basica
Do we mean with pure energy the force-carrying particles? Does pure energy consists of the forces between matter, or the force mediating particles, like the massless photons and gluon? I explicitly don´t mention the W- and Z- particles which are supposed to transmit the weak force, because they possess mass and as such they don´t are a form of pure energy, if what I said is actually pure energy
What would be pure energy ?An example of pure energy? Is electron a form of pure energy What would be pure energy,or what could be referred as the original form of energy From where all things begin Has this been found out Or the universe is thoug
What (if any) state did energy exist in prior to the big bang? I am comfortable with the idea that 'pure energy' cannot be observed, only different forms in which it manifests I can also understand that matter-antimatter interactions result in fundamental particles that ultimately conserve energy So forgive my amateur question, but is there any conception of what energy was like prior to the big bang?
If pure energy is photons, and energy is conserved, how can matter . . . 1 Photons aren't pure energy - they are a particle like all other particles Admittedly photons are massless but then so are gluons, and indeed above the electroweak phase transition temperature so are all particles So pair production from photons and annihilation into photons is just a scattering process like any other particle interaction
What happens to matter when it is converted into energy? All of them have energy, though, and the energy is conserved throughout What happens is that in these cases, the rest (or "mass") energy of the particles, proportional to their mass, is converted into mass and also kinetic energy of other particles
mass - What is Energy made of? - Physics Stack Exchange Pure energy exists out of force carriers like photons and gluons This pure energy interacts with pure matter to convey energy to it, which manifests itself as some extra matter added to it
How is it possible photons have no mass but have energy? How is it possible ? I thought photons are some kind of pure energy but I saw NASA made solar sails to create propulsion, how can you create propulsion without exhaust mass ? (Momentum equation collisions) Also how can we "create" photons ? Like you can convert something into something else but creating must be impossible
What is faster? Pure rolling or rolling with slipping? Since no body is perfectly rigid, as @Dast points out, if heating (increase in internal energy of the ball) is important the rolling case can be faster Additional response to questioner's comment about tape part way on the incline Acceleration decreases with increasing $\mu$, and $\mu$ is greater for pure rolling than for rolling with slipping
