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 disadvantageous by many authors, instead the expressions of relativistic energy and momentum should be used to express the velocity dependence in relativity, which provide the same experimental predictions. First experiments capable of detecting such relations were conducted by Walter Kaufmann, Alfred Bucherer and others between 1901 and 1915. These experiments were aimed at measuring the deflection of beta rays within a magnetic field so as to determine the mass-to-charge ratio of electrons. Since the charge was known to be velocity independent, any variation had to be attributed to alterations in the electron's momentum or mass (formerly known as transverse electromagnetic
