  2. Kater's pendulum - Wikipedia

    en.wikipedia.org/wiki/Kater's_pendulum

    Gravimeter with variant of Repsold pendulum The large increase in gravity measurement accuracy made possible by Kater's pendulum established gravimetry as a regular part of geodesy . To be useful, it was necessary to find the exact location (latitude and longitude) of the 'station' where a gravity measurement was taken, so pendulum measurements ...

  3. Riefler escapement - Wikipedia

    en.wikipedia.org/wiki/Riefler_escapement

    The most accurate models were mounted in a low pressure tank to eliminate the effect of changes in atmospheric pressure on the pendulum. They were powered by a gravity remontoire, a small weight which was wound up by an electric motor every 30 seconds, to eliminate the effect of changes in drive force on the mechanism.

  4. Kapitza's pendulum - Wikipedia

    en.wikipedia.org/wiki/Kapitza's_pendulum

    Kapitza's pendulum or Kapitza pendulum is a rigid pendulum in which the pivot point vibrates in a vertical direction, up and down. It is named after Russian Nobel Prize laureate physicist Pyotr Kapitza , who in 1951 developed a theory which successfully explains some of its unusual properties. [ 1 ]

  5. Pendulum - Wikipedia

    en.wikipedia.org/wiki/Pendulum

    "Simple gravity pendulum" model assumes no friction or air resistance. A pendulum is a device made of a weight suspended from a pivot so that it can swing freely. [1] When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position.

  6. Gravimetry - Wikipedia

    en.wikipedia.org/wiki/Gravimetry

    Gravimeter with variant of Repsold–Bessel pendulum An Autograv CG-5 gravimeter being operated. A gravimeter is an instrument used to measure gravitational acceleration. Every mass has an associated gravitational potential. The gradient of this potential is a force. A gravimeter measures this gravitational force.

  7. Anchor escapement - Wikipedia

    en.wikipedia.org/wiki/Anchor_escapement

    The backward motion of the escape wheel during part of the cycle, called recoil, is one of the disadvantages of the anchor escapement.It results in a temporary reversal of the entire wheel train back to the driving weight with each tick of the clock, causing extra wear in the wheel train, excessive wear to the gear teeth, and inaccuracy.

  9. Verge escapement - Wikipedia

    en.wikipedia.org/wiki/Verge_escapement

    In a verge pendulum clock (see picture) which appeared after the pendulum was invented in 1656, the escapement was turned 90° so the verge rod was horizontal, while the escape wheel's axis was vertical, located under the verge rod. In the first pendulum clocks the pendulum was attached to the end of the verge rod instead of the balance wheel ...
