  2. Angular acceleration - Wikipedia

    en.wikipedia.org/wiki/Angular_acceleration

    In physics, angular acceleration (symbol α, alpha) is the time rate of change of angular velocity.Following the two types of angular velocity, spin angular velocity and orbital angular velocity, the respective types of angular acceleration are: spin angular acceleration, involving a rigid body about an axis of rotation intersecting the body's centroid; and orbital angular acceleration ...

  3. 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.

  4. Equations of motion - Wikipedia

    en.wikipedia.org/wiki/Equations_of_motion

    where α is the constant angular acceleration, ω is the angular velocity, ω 0 is the initial angular velocity, θ is the angle turned through (angular displacement), θ 0 is the initial angle, and t is the time taken to rotate from the initial state to the final state.

  5. Rotation around a fixed axis - Wikipedia

    en.wikipedia.org/wiki/Rotation_around_a_fixed_axis

    Thus, the angular acceleration is the rate of change of the angular velocity, just as acceleration is the rate of change of velocity. The translational acceleration of a point on the object rotating is given by =, where r is the radius or distance from the axis of rotation.

  6. 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 ...

  7. Angular mechanics - Wikipedia

    en.wikipedia.org/wiki/Angular_mechanics

    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.

  8. Rotating reference frame - Wikipedia

    en.wikipedia.org/wiki/Rotating_reference_frame

    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. This article ...

  9. Acceleration - Wikipedia

    en.wikipedia.org/wiki/Acceleration

    For a given angular velocity, the centripetal acceleration is directly proportional to radius . This is due to the dependence of velocity v {\displaystyle v} on the radius r {\displaystyle r} . v = ω r . {\displaystyle v=\omega r.}
