Angular speed is a crucial concept in rotational motion, measuring how fast an object spins around an axis in radians per second. It differs from linear speed, which depends on radial distance, and angular velocity, which includes direction. Understanding angular speed is essential for applications in engineering, robotics, and more, as it relates to the frequency and linear speed of rotating objects like wheels and gears.
