The difference between the meaning of angular velocity and linear velocity

Angular velocity: the radian that connects the radius of a moving particle and the center of a circle and turns in unit time is called "angular velocity". The unit of angular velocity is radians per second, which is read as radians per second. It is a physical quantity that describes the speed and direction of rotation of an object or a particle around another particle. The time change rate of angular displacement of an object is called instantaneous angle
