• 16. On the concept of linear velocity and angular 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 angular velocity (also known as instantaneous angular velocity), For uniform circular motion, the angular velocity ω is a constant, which can be expressed by the ratio of the angular displacement Δ θ of the moving object and the corresponding time Δ t Linear velocity: the velocity of any point of a rigid body in circular motion about a fixed axis is called "linear velocity". It is generally defined as the instantaneous velocity of a particle (or points on an object) in curvilinear motion (including circular motion), In uniform circular motion, the linear velocity is equal to the ratio of the arc length (s) through which the moving particle passes and the time spent (△ T). That is, v = s / △ t, In uniform circular motion, although the magnitude of linear velocity does not change, its direction changes all the time. The relationship between linear velocity and angular velocity is v = ω R. the unit of linear velocity is m / s“ So the above is that the linear velocity and angular velocity refer to the velocity through the radian? Is there a simpler, more accessible definition?
