Why does varying the spacing between adjacent dominoes change the velocity of the wave?
Answer Hello Maddie: Thanks for your question! The speed of the wave will vary on the distance between the dominoes because of the time it takes for the top of the domino to rotate in its arc towards the next domino. So, the longer the distance, the slower the wave speed. There is a lot of speculation on this topic regarding your other questions, so review: http://www.physicsforums.com/archive/index.php/t-10713.html I this info helps!
