Homework Statement
what is the difference between angular velocity and angular frequency?
Angular velocity is a vector quantity that measures the rate of change of angular displacement with respect to time. On the other hand, angular frequency is a scalar quantity that represents the number of rotations or revolutions per unit time.
Angular frequency is equal to angular velocity divided by 2π. In other words, angular velocity is the product of angular frequency and 2π.
Angular velocity is typically measured in radians per second (rad/s) or degrees per second (°/s). It can also be expressed in revolutions per minute (RPM) or revolutions per second (RPS).
The direction of angular velocity is perpendicular to the plane of rotation, following the right-hand rule. This means that if you curl the fingers of your right hand in the direction of rotation, your thumb will point in the direction of the angular velocity vector.
Angular velocity plays a crucial role in rotational motion, as it determines the speed and direction of the rotation. Higher angular velocity results in faster rotation, while a change in the direction of angular velocity can cause a change in the direction of rotation.
