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
Center-of-momentum frame is given below – in a two-body collision, not necessarily elastic (where "kinetic energy" is conserved). The COM frame can be used to find the momentum of the particles much easier than in a lab frame: the frame where the measurement or calculation is done. The situation is analyzed using Galilean transformations and conservation of momentum (for generality, rather than kinetic energies alone), for two particles of mass "m" and "m", moving at initial velocities (before collision) u and u respectively. The transformations are applied to take the velocity of the frame from the velocity of each particle from the
