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.
In 1970, four years before Erno Rubik invented the 3Ã3, Larry Nichols invented a 2Ã2 cube that used magnets to hold it together and received his patent two years later. A spherical 3x3x3 âamusement deviceâ was patented also in 1970 by Frank Fox, however neither of these concepts took off.
