  2. Rotational frequency - Wikipedia

    en.wikipedia.org/wiki/Rotational_frequency

    Rotational frequency, also known as rotational speed or rate of rotation (symbols ν, lowercase Greek nu, and also n), is the frequency of rotation of an object around an axis. Its SI unit is the reciprocal seconds (s −1 ); other common units of measurement include the hertz (Hz), cycles per second (cps), and revolutions per minute (rpm).

  5. Cadence (cycling) - Wikipedia

    en.wikipedia.org/wiki/Cadence_(cycling)

    Cadence (cycling) In cycling, cadence is a measure of rotational speed of the crank, expressed in units of revolutions per minute (r/min or rpm). In other words, it is the pedalling rate at which a cyclist is turning the pedals. Cadence is directly proportional to wheel speed, but is a distinct measurement and changes with gearing.

    en.wikipedia.org/wiki/Scoliosis

    Frequency. 3% [5][6] Scoliosis (pl.: scolioses) is a condition in which a person's spine has an irregular curve [2] in the coronal plane. The curve is usually S- or C-shaped over three dimensions. [2][7] In some, the degree of curve is stable, while in others, it increases over time. [3] Mild scoliosis does not typically cause problems, but ...

    en.wikipedia.org/wiki/Gyroscopic_exercise_tool

    A gyroscopic exercise tool is a specialized device used in physical therapy to improve wrist strength and promote the development of palm, wrist, forearm, and finger muscles. It can also be used as a unique demonstration of some aspects of rotational dynamics. The device consists of a tennis ball -sized plastic or metal shell surrounding a free ...

    en.wikipedia.org/wiki/Rigid_body_dynamics

    In the physical science of dynamics, rigid-body dynamics studies the movement of systems of interconnected bodies under the action of external forces.The assumption that the bodies are rigid (i.e. they do not deform under the action of applied forces) simplifies analysis, by reducing the parameters that describe the configuration of the system to the translation and rotation of reference ...
