Creatorverse the tablet’s touch screen to create designs that could then be animated and set into motion using various physics-based properties and attributes (such as friction, speed and force). All creations can then be shared among other creators, who also have the capability to remix, expand or even dismantle other community creations. Inspiration for Creatorverse, including the logo, originated from the popular device Newton's cradle, which demonstrates conservation of momentum and energy via a series of swinging spheres. Creatorverse Creatorverse was a physics-based sandbox creation game for the Apple iOS, Android, Kindle Fire, and Kindle Fire HD that was released in
Tests of relativistic energy and momentum instance, the rest energy of electrons and positrons is 0.51 MeV respectively. When a photon interacts with an atomic nucleus, electron-positron pairs can be generated in case the energy of the photon matches the required threshold energy, which is the combined electron-positron rest energy of 1.02 MeV. However, if the photon energy is even higher, than the exceeding energy is converted into kinetic energy of the particles. The reverse process occurs in electron-positron annihilation at low energies, in which process photons are created having the same energy as the electron-positron pair. These are direct examples of formula_18 (mass–energy equivalence). There
