Constant Angular Velocity

The object moves with constant angular velocity around the circle.

Like the stars, the spiral arms rotate around the center, but they do so with constant angular velocity.

The alignment ensures constant angular velocity at all joint angles.

This results in a constant angular velocity, , which is independent of .

This ensures that the motion of one gear is transferred to the other at locally constant angular velocity.

Imagine that some observer rotates with constant angular velocity about some axis.

Imagine a disk of radius R rotating with constant angular velocity .

Here, we use the constant angular velocity of a circular orbit in Newtonian physics:

For example, a flywheel is used to maintain constant angular velocity of the crankshaft in a reciprocating engine.

So we come to another familiar example: the inertial acceleration observed in a frame rotating at constant angular velocity Φ.

As the disk rolls, the point P of rolling contact describes a circle that oscillates with a constant angular velocity .

Constant angular velocity or Standard Play discs supported several unique features such as freeze frame, variable slow motion and reverse.

Hence, the linear velocity is not constant, though some would think that the "constant angular velocity" principle applied on all disk-shaped media.

Constant angular velocity (CAV)

The flexibility of a CVT allows the input shaft to maintain a constant angular velocity over a range of output velocities.

The sinusoidal motion, cosinusoidal velocity, and sinusoidal acceleration (assuming constant angular velocity) results in smoother operation.

One of the biggest obstacles in this re-design (after its significantly higher cost) was the short 30-minute-per-side capacity of Constant Angular Velocity or random access laserdiscs.

The carousel rotates at a constant angular velocity represented by the vector Ω with magnitude ω, pointing upward according to the right-hand rule.

This is called constant angular velocity (CAV) because it takes the same amount of time for a turn of the 360 degrees of the disk at all times.

Constant angular velocity (CAV) keeps the disk spinning at a fixed rate, measured in revolutions per minute (RPM).

Apple eventually reverted to constant angular velocity on HD floppy disks with their later machines, still unique to Apple as they supported the older variable-speed formats.

The GD-ROM in the Dreamcast works in constant angular velocity (CAV) mode, like the majority of modern optical drives.

For instance, when holding onto a carousel that turns at constant angular velocity you experience a radially inward (centripetal) proper-acceleration due to the interaction between the hand-hold and your hand.

A drive or disc operating in CAV mode maintains a constant angular velocity, contrasted with a constant linear velocity (CLV).

That is in fact what is seen in the second animation, in which the motion is mapped to a coordinate system that is rotating at a constant angular velocity.
