V= r (omega): blog 7 :)



In September, the 'Iolani Dance Team and Marching Band performed in the Aloha Week Parade! :) As if dancing 3.5 miles doesnt sound hard enough, sometimes the roads we dance on have bends and turns! We have to stay in our lines NO MATTER WHAT, so to help us around these turns, we use physics! :)
Linear speed depends on radial distance from the center and rotational speed.
If we are making a left turn, then the dancers on the left side must travel very little, and almost stay in place as we round the turn. The dancers on the right, however, must make long strides while maintaining our straight lines. While both sides have the same rotational speed, the radial speeds are different because the dancers on the right are traveling at a faster speed, with a larger radius.
