In physics, angular velocity (symbol ω or , the lowercase Greek letter omega), also known as angular frequency vector, [1] is a pseudovector representation of how the angular position or orientation of an object changes with time, i.e. how quickly an object rotates (spins or revolves) around an axis of rotation and how fast the axis itself changes direction.
A diagram of angular momentum. Showing angular velocity (Scalar) and radius. In physics, angular mechanics is a field of mechanics which studies rotational movement. It studies things such as angular momentum, angular velocity, and torque. It also studies more advanced things such as Coriolis force [1] and Angular aerodynamics.
Short title: Angular velocity: Image title: Diagram of a particle at radius vector r with velocity V showing the radial and tangential components of the velocity, the angle of the radius vector with respect to the x axis and the angle of the velocity vector with respect to the radius vector.
Scaling for angular velocity [ edit ] From the foregoing, you can see that the time domain equations are simply scaled forms of the angle domain equations: x {\displaystyle x} is unscaled, x ′ {\displaystyle x'} is scaled by ω , and x ″ {\displaystyle x''} is scaled by ω² .
The diagram illustrates a four-wheel vehicle, in which the front axle is located a metres ahead of the centre of gravity and the rear axle is b metres towards the rear from the center of gravity. The body of the car is pointing in a direction θ {\displaystyle \theta } (theta) while it is travelling in a direction ψ {\displaystyle \psi } (psi).
In classical mechanics, the Euler acceleration (named for Leonhard Euler), also known as azimuthal acceleration [8] or transverse acceleration [9] is an acceleration that appears when a non-uniformly rotating reference frame is used for analysis of motion and there is variation in the angular velocity of the reference frame's axis.

The above development is a special case of general rotational motion. In the general case, angular displacement, angular velocity, angular acceleration, and torque are considered to be vectors. An angular displacement is considered to be a vector, pointing along the axis, of magnitude equal to that of .
The diagram shows lift being produced on a back-spinning ball. ... where ω is the angular velocity of the cylinder (in rad/s) and r is the radius of the cylinder ...
