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 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
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 happens to matter when it is converted into energy? Matter can be converted into Energy An example of this is a nuclear reaction What happens to the matter in the process? Do the atoms subatomic particles just vanish? Any insights into this process are appreciated
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 μ μ, and μ μ is greater for pure rolling than for rolling with slipping
newtonian mechanics - Energy conservation for a rolling rigid body . . . At position A, body will have rolling kinetic energy and by conservation of energy, this rolling kinetic energy is converted into potential energy at position B $$\frac {1} {2}mv^2 (1+\frac {k^2} {r^2})=mgh$$ where k is radius of gyration I solved this equation for conservation of energy But it turns out this equation isn't correct
