Angular velocity is a measure of the rate at which an object rotates or moves in a circular path. It is defined as the change in angular displacement over time.
Angular velocity is calculated by dividing the change in angular displacement by the change in time. It is measured in radians per second (rad/s) or degrees per second (deg/s).
Angular velocity measures the rotation of an object, while linear velocity measures the straight-line motion of an object. Angular velocity is expressed in angular units while linear velocity is expressed in linear units.
Angular velocity and centripetal acceleration are directly proportional. This means that as angular velocity increases, so does centripetal acceleration. This relationship is expressed by the equation a = ω²r, where a is the centripetal acceleration, ω is the angular velocity, and r is the radius of the circular path.
Angular velocity is used in a variety of fields, such as engineering, physics, and astronomy. It is used to study the motion of planets and stars, design roller coasters and other amusement park rides, and analyze the rotation of machinery and vehicles.
