SUMMARY
A particle moving in a circle exhibits angular momentum defined by the equation L = m r² ω, where L is angular momentum, m is mass, r is radius, and ω is angular speed. When the radius of the circle is doubled while maintaining the same angular speed, the angular momentum also doubles. This conclusion is based on the direct relationship between radius and angular momentum in circular motion.
