angular velocity
This term is a technical specification used primarily in physics, engineering, and astronomy to describe rotational motion. It differs from linear velocity by focusing on the change in angle over time rather than the distance traveled along a path. In a professional or academic register, it is almost always paired with specific units of measurement, most commonly radians per second (rad/s).
Because it is a vector quantity, the term implies a specific direction of rotation, typically defined by the right-hand rule. In practical application, it is used to calculate the centripetal acceleration of an object, making it a foundational concept for understanding everything from spinning turbines to planetary orbits.
