Negative angular velocity refers to the rotation or spinning of an object in the opposite direction to the conventionally defined positive angular velocity.
Angular velocity is a vector quantity that represents the rate of change of angular displacement of an object per unit of time. It describes how quickly an object is rotating or spinning. Positive angular velocity indicates a counterclockwise rotation, while negative angular velocity indicates a clockwise rotation.
The direction of angular velocity is determined by the right-hand rule. If you extend your right hand and curl your fingers in the direction of rotation, your thumb will point in the direction of the positive angular velocity. If the object rotates in the opposite direction, your thumb will point in the direction of the negative angular velocity.
In summary, negative angular velocity indicates a clockwise rotation, while positive angular velocity indicates a counterclockwise rotation when viewed from a specified reference point.
