  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 the 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. Magnus effect - Wikipedia

    en.wikipedia.org/wiki/Magnus_effect

    Participants in other sports played with a ball also take advantage of this effect. ... where ω is the angular velocity of the cylinder (in rad/s) and r is the ...

  4. Tennis racket theorem - Wikipedia

    en.wikipedia.org/wiki/Tennis_racket_theorem

    The magnitude of the angular momentum and the kinetic energy of a spinning object are both conserved. As a result, the angular velocity vector remains on the intersection of two ellipsoids. Here, the yellow ellipsoid is the angular momentum ellipsoid, and the expanding blue ellipsoid is the energy ellipsoid.

  5. 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 .

  6. 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 ...

  7. Bouncing ball - Wikipedia

    en.wikipedia.org/wiki/Bouncing_ball

    The ball's angular velocity will be increased after impact, but its horizontal velocity will be decreased. The ball will not exceed its original height and will keep spinning in the same direction. If the surface is inclined by some amount θ , the entire diagram would be rotated by θ , but the force of gravity would remain pointing downwards ...

  8. Coriolis force - Wikipedia

    en.wikipedia.org/wiki/Coriolis_force

    The Coriolis force acts in a direction perpendicular to two quantities: the angular velocity of the rotating frame relative to the inertial frame and the velocity of the body relative to the rotating frame, and its magnitude is proportional to the object's speed in the rotating frame (more precisely, to the component of its velocity that is ...

  9. Kinematics - Wikipedia

    en.wikipedia.org/wiki/Kinematics

    Angular velocity: the angular velocity ω is the rate at which the angular position θ changes with respect to time t: = The angular velocity is represented in Figure 1 by a vector Ω pointing along the axis of rotation with magnitude ω and sense determined by the direction of rotation as given by the right-hand rule.
