Angular Velocity

Angular velocity is a measure of the rate at which an object rotates or revolves around a fixed axis. It is typically measured in radians per second (rad/s) or degrees per second (deg/s) and represents the magnitude of the angular displacement over a given time period.

Angular velocity plays an important role in various fields of physics and engineering, including mechanics, robotics, and astronomy. For example, it is used to describe the motion of rotating machinery such as engines, turbines, and motors, as well as the movement of celestial objects such as planets and stars.

In addition, understanding angular velocity is crucial for the development of technologies such as gyroscopes, which use the principle of conservation of angular momentum to maintain orientation and stability in various applications, including navigation systems, spacecraft, and drones.

The formula for determining the angular velocity is defined as:
$$w$$ $$=$$ $$\dfrac{\theta}{t}$$
$$\theta$$: the change of angular rotation
$$w$$: the angular velocity/speed
$$t$$: the change in time
The SI unit of angular velocity is: $$radian/second \text{ }(rad/s)$$
