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.
Rubik's Cube was first called the Magic Cube (Buvuos Kocka) in Hungary. The puzzle had not been patented internationally within a year of the original patent. Patent law then prevented the possibility of an international patent.
