📚 Topic Summary
This lab activity explores the fundamental relationships between linear and angular motion. Specifically, it focuses on verifying the equations $v = rω$ and $a = rα$, where $v$ is the linear velocity, $r$ is the radius, $ω$ is the angular velocity, $a$ is the linear acceleration, and $α$ is the angular acceleration. By measuring the linear and angular speeds and accelerations of a rotating object, you can experimentally confirm these theoretical relationships. This activity reinforces the link between rotational and translational kinematics, providing a deeper understanding of circular motion.
