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.
The place was Budapest, the capital of Hungary. The inventor's name is now a household word, Rubik's Cube. Although 1974 marks the inauguration of the Cube, the processes that led to the invention began a few years earlier. At the time, Erno Rubik was a lecturer at the Department of Interior Design at the Academy of Applied Arts and Crafts in Budapest.
