Angular velocity is defined as:

Angular velocity is defined as:

• A. The rate at which an object rotates about an axis
• B. The linear speed of a point on the object
• C. The distance from the axis to the object's center
• D. The total energy of the rotating body

Answer: (A)

Angular velocity is the rate at which an object rotates about an axis. It tells you how quickly the rotation angle changes with time, typically in radians per second, and it has a direction given by the axis (often described using the right-hand rule). This is different from the linear speed of a point on the object, which depends on how far that point is from the axis (v = ωr). The distance from the axis to the object's center is the radius, not the rate of rotation, and the total energy of the rotating body refers to rotational kinetic energy, not how fast the rotation occurs. So the best match is the rate of rotation about an axis.
