A Kater's pendulum is a reversible free swinging pendulum invented by British physicist and army captain Henry Kater in 1817 (made public on 29 January 1818), [1] for use as a gravimeter instrument to measure the local acceleration of gravity.
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.
"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.
Now it became possible to measure gravity more accurately. Vening Meinesz started with measuring gravity all over the Netherlands, for which a network of 51 monitoring stations was created. This became a success, which encouraged him to do measurements at sea. A perfected gravimeter, hanging in a "swing", was designed. The experiment was ...
A pendulum is a body suspended from a fixed support such that it freely swings back and forth under the influence of gravity. 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 towards the equilibrium position.
A trifilar pendulum is a platform supported by three wires designed to oscillate in torsion around its vertical centroidal axis. [19] The period of oscillation of the trifilar pendulum yields the moment of inertia of the system. [20]
"Looking at nature, there are so many cycles, so many things that are kind of going back and forth, like night and day …. changes of seasons, and the waxing and waning of the moon," noted Karp.
The same teams repeated a dual experiment during the annular solar eclipse of January 26, 2009, this time outside of the umbra, with the same significant correlation between the behavior of light torsion balances and a Foucault pendulum. [18] They also registered similar anomalies using a Foucault pendulum and a very light torsion balance, both ...
