Constant acceleration motion can be represented in motion graphs which represent velocity, acceleration, and distance as functions of time. These graphs are useful for calculating information about motion using the slopes of the curves in each plot.
Rubik's Cube is a 3-D combination puzzle invented in 1974 by Hungarian sculptor and professor of architecture ErnÅ Rubik.
However, prior to the invention of the Rubikâs Cube, an earlier attempt at a 2x2x2 rotational cube was invented by Larry Nichols in 1970, who later attempted to sue the Rubikâs Cubeâs licensee, Ideal Toy Corp., in 1984 for patent infringement.t was eventually licensed to Ideal Toy Corp. in 1979 and rebranded as the Rubikâs Cube before its appearance internationally in 1980. Rubikâs Cube was patented in 1975. A year after Erno Rubik invented his then-named âMagic Cube,â he patented it in Hungary.
