  2. Rotating spheres - Wikipedia

    en.wikipedia.org/wiki/Rotating_spheres

    The rotating observers see the spheres in circular motion with angular rate ω S = ω I − ω R (S = spheres). That is, if the frame rotates more slowly than the spheres, ω S > 0 and the spheres advance counterclockwise around a circle, while for a more rapidly moving frame, ω S < 0, and the spheres appear to retreat clockwise around a ...

  3. Absolute rotation - Wikipedia

    en.wikipedia.org/wiki/Absolute_rotation

    Figure 2: Two spheres tied with a string and rotating at an angular rate ω. Because of the rotation, the string tying the spheres together is under tension. Newton also proposed another experiment to measure one's rate of rotation: using the tension in a cord joining two spheres rotating about their center of mass.

  4. Centrifugal force - Wikipedia

    en.wikipedia.org/wiki/Centrifugal_force

    Newton suggested two arguments to answer the question of whether absolute rotation can be detected: the rotating bucket argument, and the rotating spheres argument. [5] According to Newton, in each scenario the centrifugal force would be observed in the object's local frame (the frame where the object is stationary) only if the frame were ...

  5. Inertial frame of reference - Wikipedia

    en.wikipedia.org/wiki/Inertial_frame_of_reference

    Figure 2: Two spheres tied with a string and rotating at an angular rate ω. Because of the rotation, the string tying the spheres together is under tension. Figure 3: Exploded view of rotating spheres in an inertial frame of reference showing the centripetal forces on the spheres provided by the tension in the tying string.

  6. Sphere - Wikipedia

    en.wikipedia.org/wiki/Spheres

    The set of all spheres satisfying this equation is called a pencil of spheres determined by the original two spheres. In this definition a sphere is allowed to be a plane (infinite radius, center at infinity) and if both the original spheres are planes then all the spheres of the pencil are planes, otherwise there is only one plane (the radical ...

  7. Celestial mechanics - Wikipedia

    en.wikipedia.org/wiki/Celestial_mechanics

    Dynamics of the celestial spheres concerns pre-Newtonian explanations of the causes of the motions of the stars and planets. Dynamical time scale; Ephemeris is a compilation of positions of naturally occurring astronomical objects as well as artificial satellites in the sky at a given time or times. Gravitation

  8. Bucket argument - Wikipedia

    en.wikipedia.org/wiki/Bucket_argument

    The shape of the surface of a rotating liquid in a bucket can be determined using Newton's laws for the various forces on an element of the surface. For example, see Knudsen and Hjorth. [16] The analysis begins with the free body diagram in the co-rotating frame where the water appears stationary.

    For any natural number ⁠ ⁠, an ⁠ ⁠-sphere of radius ⁠ ⁠ is defined as the set of points in ⁠ (+) ⁠-dimensional Euclidean space that are at distance ⁠ ⁠ from some fixed point ⁠ ⁠, where ⁠ ⁠ may be any positive real number and where ⁠ ⁠ may be any point in ⁠ (+) ⁠-dimensional space.
