Recently scientists have found that the speed of a domino is dependent on friction.
David Cantor, a researcher in Quebec, Canada, thought that dominoes were fun to play with and so he decided to start conducting researching about them. With Kajetan Wojtacki, who works at Institute of Fundamental Technological Research, he was able to find out more about dominoes.
The team of two used a digital model to see the dominoes collapsing in slow motion and analyze their movement. Before working, Cantor said “[i]t’s a problem that is so natural. Everybody plays with dominoes.” As they studied, they noticed the two places that the friction happens, in a Science News for Students article it says, “[t]he dominoes rub together as they collide. They also slide along the surface on which they sit.”
Cantor and Wojtacki found out how to get a different speed of the dominos as pushed and they tested how apart it would be as well. Dominos have different textures, like some are smoother than others and some are rough. The slicker ones have less friction meaning, as the dominos fall, they will fall fast and ones with more friction are harder to collapse.
How far apart the dominoes are, also affects the movement of it; if too far apart, the dominoes will hardly touch each other. The pair originally got inspired by the Youtuber Destin Sandlin, who makes experiments with dominoes like Cantor and Wojitacki have done with friction. Another video idea was an American domino record made by the same person, Destin Sandlin. It was a 250,000-domino record.
This pair really got creative to think about the plain old toy, dominoes. What can you do with dominos with playing with them the classic way?
