  2. Angular velocity - Wikipedia

    en.wikipedia.org/wiki/Angular_velocity

    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.

  3. Angular frequency - Wikipedia

    en.wikipedia.org/wiki/Angular_frequency

    Angular frequency (or angular speed) is the magnitude of the pseudovector quantity angular velocity. [1] Angular frequency can be obtained multiplying rotational frequency, ν (or ordinary frequency, f) by a full turn (2 π radians): ω = 2 π rad⋅ν. It can also be formulated as ω = dθ/dt, the instantaneous rate of change of the angular ...

    Angular momenta of a classical object. Left: intrinsic "spin" angular momentum S is really orbital angular momentum of the object at every point, right: extrinsic orbital angular momentum L about an axis, top: the moment of inertia tensor I and angular velocity ω (L is not always parallel to ω) [6] bottom: momentum p and its radial position r ...

  5. Angular velocity tensor - Wikipedia

    en.wikipedia.org/wiki/Angular_velocity_tensor

    In general, the angular velocity in an n-dimensional space is the time derivative of the angular displacement tensor, which is a second rank skew-symmetric tensor.. This tensor Ω will have n(n−1)/2 independent components, which is the dimension of the Lie algebra of the Lie group of rotations of an n-dimensional inner product space.

    One particle: N particles: One dimension ^ = ^ + = + ^ = = ^ + (,,) = = + (,,) where the position of particle n is x n. = + = = +. (,) = /.There is a further restriction — the solution must not grow at infinity, so that it has either a finite L 2-norm (if it is a bound state) or a slowly diverging norm (if it is part of a continuum): [1] ‖ ‖ = | |.

  7. Euler's equations (rigid body dynamics) - Wikipedia

    Also in some frames not tied to the body can it be possible to obtain such simple (diagonal tensor) equations for the rate of change of the angular momentum. Then ω must be the angular velocity for rotation of that frames axes instead of the rotation of the body. It is however still required that the chosen axes are still principal axes of ...

    the omega baryon; the arithmetic function counting a number's prime factors counted with multiplicity; the density parameter in cosmology; the first uncountable ordinal (also written as ω 1) Chaitin's constant for a given computer program; the vacuum state in quantum field theory; represents: angular velocity / radian frequency (rad/sec)

  9. Angular mechanics - Wikipedia

    en.wikipedia.org/wiki/Angular_mechanics

    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 .
