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.he Rubikâs Cube has finally hit its mid-life crisis as it reaches its 40th anniversary this year. Invented in 1974 by Hungarian sculptor and architecture professor Erno Rubik, the Rubikâs cube has challenged and frustrated countless numbers of players who have ever picked up the 3-D toy puzzle.
