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 ...
Persoz pendulum device. The pendulum consists of balls which rest on the coating under test and form the fulcrum. The Persoz pendulum is very similar to the Konig pendulum. Both employ the same principle, that is the softer the coating the more the pendulum oscillations are damped and the shorter the time needed for the amplitude of oscillation ...
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.
Cavendish's equipment was remarkably sensitive for its time. [10] The force involved in twisting the torsion balance was very small, 1.74 × 10 −7 N, [13] (the weight of only 0.0177 milligrams) or about 1 ⁄ 50,000,000 of the weight of the small balls. [14]

English: Diagram of simple gravity pendulum, an ideal model of a pendulum. It consists of a massive bob suspended by a weightless rod from a frictionless pivot, without air friction. When given an initial impulse, it oscillates at constant amplitude, forever
