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 raced home and created a prototype held together with paper clips and rubber bandsâa structure consisting of 21 smaller cubelets, adhered to a rounded interlocking mechanism. âIt was very emotional,â the inventor told CNN in 2012.
