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.
Erno Rubik: how we made Rubikâs Cube. Erno Rubik: âI experimented in my motherâs flat, making a prototype out of wood, rubber bands and paper clipsâ. âThe first time it took me weeks: there are 43 quintillion permutations!â â¦ Erno Rubik with his daughter Anna in 1981.
