In http://www.answers.com/topic/optical-storage, constant angular velocity (CAV) is a qualifier for the rated speed of an http://www.answers.com/topic/optical-disc-drive, and may also be applied to the writing speed of recordable http://www.answers.com/topic/optical-disc. A drive or disc operating in CAV mode maintains a constant http://www.answers.com/topic/angular-velocity, contrasted with a http://www.answers.com/topic/clv (CLV). When playing back music, a http://www.answers.com/topic/compact-disc (CD) employs CLV to maintain a constant data rate. The motor speed decreases from 495 to 212 rpm as the read head moves away from the center to keep the disc moving past the read head at a constant linear velocity. High speed CD and DVD Drives use CAV. CAV was used in the LaserDisc format for interactive titles, as well as special editions of certain films. CAV allowed for perfect still frames, as well as random access to any given frame on a disc. Playing time, however, was cut in half from 60 minutes to 30 minutes. CAV is used with Nintendo GameCube Game Disc and Wii Optical
The derivative of angular velocity is angular acceleration. It is calculated by taking the derivative of the angular velocity function with respect to time. Mathematically, angular acceleration () is calculated as the rate of change of angular velocity () over time.
To determine the angular acceleration when given the angular velocity, you can use the formula: angular acceleration change in angular velocity / change in time. This formula calculates how quickly the angular velocity is changing over a specific period of time.
To convert angular velocity to linear velocity, you can use the formula: linear velocity = angular velocity * radius. This formula accounts for the fact that linear velocity is the distance traveled per unit time (similar to speed), while angular velocity is the rate of change of angular position. By multiplying angular velocity by the radius of the rotating object, you can calculate the linear velocity at the point of interest on that object.
Linear velocity is directly proportional to the radius at which the object is moving and the angular velocity of the object. The equation that represents this relationship is v = rω, where v is the linear velocity, r is the radius, and ω is the angular velocity. As the angular velocity increases, the linear velocity also increases, given the same radius.
To calculate angular velocity from linear velocity, you can use the formula: Angular velocity Linear velocity / Radius. This formula relates the speed of an object moving in a circular path (angular velocity) to its linear speed and the radius of the circle it is moving in.
To determine the angular velocity from linear velocity, you can use the formula: Angular velocity Linear velocity / Radius. This formula relates the speed of an object moving in a circular path (linear velocity) to how quickly it is rotating around the center of the circle (angular velocity).
There are several, what is it that you want to calculate? The "natural" units for angular velocity are radians/second. The relationship between linear velocity and angular velocity is especially simple in this case: linear velocity (at the edge) = angular velocity x radius.
Yes, angular velocity is a vector quantity
The angle between angular and tangential velocity is 90 degrees. Angular velocity is perpendicular to the direction of tangential velocity in a circular motion.
Angular velocity and tangential velocity are related in a rotating object by the equation v r, where v is the tangential velocity, r is the radius of the object, and is the angular velocity. This means that the tangential velocity is directly proportional to the radius and the angular velocity of the object.
To find the linear velocity from angular velocity, you can use the formula: linear velocity angular velocity x radius. This formula relates the speed of an object moving in a circle (angular velocity) to its speed in a straight line (linear velocity) based on the radius of the circle.
No, uniform angular velocity implies that an object is moving in a circle at a constant rate. Since acceleration is defined as any change in velocity (either speed or direction), if the angular velocity is constant, there is no acceleration present.
