Kater's pendulum - Wikipedia
A Kater's pendulum is a reversible free swinging pendulum invented by British physicist and army captain Henry Kater in 1817, published 29th January 1818 [1] for use as a gravimeter instrument to measure the local acceleration of gravity.
2003年9月12日 · Kater used this device to measure the acceleration of gravity at various locations in England. He also determined the length of what was called the second’s pendulum, i.e., a pendulum whose half-period is one second.

To overcome this difficulty we can turn a physical pendulum into a so-called reversible (Kater's) 1 pendulum. Two knife-edge pivot points and two adjustable masses are positioned on the rod so that the period of swing is the same from either edge.

1 天前 · Kater's pendulum was used as a gravimeter to measure the local acceleration of gravity with greater accuracy than an ordinary pendulum, because it avoids having to measure l. It was popular from its invention in 1817 until the 1950’s, when began to be possible to directly measure the acceleration of gravity during free fall using a Michelson ...
Kater’s Pendulum Local value of gcan be quite precisely measured using a pendulum of known length. In practice, however, it is not easy to get a very precise measurement of the location of the center of mass of an extended object. Several clever schemes exist to overcome that by adjusting the arrangement of
Kater's pendulum - Oxford Reference
A complex pendulum designed by Henry Kater (1777–1835) to measure the acceleration of free fall. It consists of a metal bar with knife edges attached near the ends and two weights that can slide between the knife edges. The bar is pivoted from each knife edge in turn and the positions of the weights are adjusted so that the period of the ...

2023年3月17日 · Kater’s pendulum is a type of reversible pendulum used to determine the value of the acceleration due to gravity (g) at a specific location. It was invented by Captain Henry Kater in 1817, and it remains an important scientific instrument to this day.
Our Pendulum was designed to be transportable when packed in a wooden box and to swing from a knife edge support clamped to another surface. The ends of the pendulum are formed into narrow rods so the swing can be timed precisely by the rod breaking a light-beam sensor to trigger an electronic switch.
The Kater Pendulum The reversibility of point O and P described above is the principle of the reversible pendulum, invented by Kater to measure gravity with high accuracy. Kater’s pendulum consists of a long bar, equipped with two fixed knife edges at an accurately known distance L, and with some moveable masses positioned along the bar.
The Kater Pendulum 2 weights for basic result with random error assessed; 3 weights with full assessment of systematic error. Scientific Objective To measure the acceleration of gravity at a location in the second year laboratory with as much precision as possible (hopefully to at least 1 in 104), by timing the swing
