## What is the principle of Kater pendulum?

According to the principle of KAter’s pendulum, when the pendulum is suspended upside down from the centre of its oscillation, the period of the swing remains unchanged and the new oscillation centre is the old pivot point.

Why Kater’s pendulum is accurate?

The point of suspension also is not accurately determined in a simple pendulum. So once a near equality in time period is obtained on both sides of the centre of gravity of the metallic bar, determining the length of the pendulum becomes more accurate, and so does determining the acceleration g due to gravity.

Why is Keter’s pendulum used and how does it perform better than a simple pendulum?

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.

### Is Kater pendulum a simple pendulum?

special reversible compound pendulum called Kater’s pendulum is designed to measure the value of g, the acceleration of gravity.

Which pendulum is more accurate?

Treating a pendulum as a compound pendulum for calculations is more difficult, but it yields more accurate predictions because the simple pendulum model is idealized. Every physical pendulum is in reality a compound pendulum, because the rod is never massless.

Why katers pendulum is called reversible?

A reversible pendulum is a special design of a normal physical pendulum. The reduction in the length of the pendulum then matches the distance between the two mounting points. This makes it easier to determine the local acceleration due to gravity from the period of oscillation and the reduced pendulum length.

## Why is Kater pendulum better than bar pendulum?

Why? – Quora. If it’s just some random bar pendulum, then a Kater’s pendulum is enormously better, because it incorporates a bunch of clever ideas to make the effective length easy to measure.

Which g value is more accurate?

I would say that the simple pendelum is the original way of determining g.

What are the disadvantages of simple pendulum over bar pendulum?

The drawbacks of simple pendulum are as follows: a) The simple pendulum can’t have a weightless, heavy point mass bob with inextensible string as we assumed. b) The motion of the bob is not strictly linear. c) The resistance and buoyancy of air affects the motion of the bob which is supposed to be negligible.

### Which is more accurate katers pendulum or bar pendulum?

If it’s just some random bar pendulum, then a Kater’s pendulum is enormously better, because it incorporates a bunch of clever ideas to make the effective length easy to measure.

What is difference between bar pendulum and Kater’s pendulum?

Kater’s pendulum is just a double-ended bar pendulum which uses a clever trick to avoid the necessity of doing a painstaking survey of where all the mass is in the bar to calculate the effective length, which is what you need to use the pendulum equation to find g from T.

What is Kater’s Pendulum?

Kater’s pendulum, shown in Fig. 1, is a physical pendulum composed of a metal rod 1.20 m in length, upon which are mounted a sliding metal weight W 1, a sliding wooden weight W 2, a small sliding metal cylinder w, and two sliding knife edges K 1 and K 2 that face each other. Each of the sliding objects can be clamped in place on the rod.

## What is Kater’s experiment?

What is the function of K1 and K2 in pendulum?

Its function is to provide as near equal air resistance to swinging as possible in either suspension, which happens if W 1 and W 2, and separately K 1 and K 2, are constrained to be equidistant from the ends of the metal rod. The centre of mass G can be located by balancing the pendulum on an external knife edge.

Who first used the reversible pendulum to measure g?

1 The reversible pendulum was first used to measure g by Captain Henry Kater: H. Kater, Philos Trans Roy Soc London 108, 33 (1818). 2 B. Crummett, The Physics Teacher 28, 291 (1990).
