The rotational motion of a strongly coupled unmagnetized 1-D-dusty plasma ring was studied. The particles rotated within the ring-shaped potential that was formed using a circular grooved electrode with a center post. Particle position data from the rotating dust ring were analyzed and the angular velocity of the particles was calculated. The rotation rate of the ring depended on the number of particles, the interparticle spacing, and the shape of the potential well. The driving force for rotation was also examined.
