# How does Barton pendulum work?

## How does Barton pendulum work?

All objects have a natural frequency of vibration or resonant frequency. If you force a systemâ€”in this case a set of pendulumsâ€”to oscillate, you get a maximum transfer of energy, i.e. maximum amplitude imparted, when the driving frequency equals the resonant frequency of the driven system.

How do you make a simple pendulum?

What to do:

1. Tie a weight onto the end of the piece of string.
2. Make a loop at the other end of the string.
3. Screw the hook into the piece of wood and balance the wood between the backs of two chairs.
4. Put the loop of string over the hook.
5. Start the weight swinging and time how long it takes to make 20 swings.

### Which pendulum has the greatest amplitude?

As X is swung all the other pendulums begin to vibrate, but pendulum C has the greatest amplitude as it has the same length and therefore the same natural frequency as X.

Why does length affect the frequency of a pendulum?

How does the length of a pendulum’s string affect its period? (Answer: A pendulum with a longer string has a longer period, meaning it takes a longer time to complete one back and forth cycle when compared with a pendulum with a shorter string.

## What is a resonating frequency?

Resonant frequency is the oscillation of a system at its natural or unforced resonance. Resonance occurs when a system is able to store and easily transfer energy between different storage modes, such as Kinetic energy or Potential energy as you would find with a simple pendulum.

What is the best material for a pendulum?

Superior Energy Conductivity: Sterling silver and copper are the two highest energy conductive materials that exist. A pendulum made with either is predictably, consistently sensitive to subtle energy vibrations in a way that other metals are not.

### How do you make a Foucault pendulum at home?

Here’s how to make a Foucault pendulum:

1. Fill the sack with sand.
2. Check that the sack has no holes by lifting it up and gently shaking it.
3. Seal the sack with the cord.
4. Hang the sack from the high structure.
5. Poke a hole in the bottom of the sack with the nail.
6. Seal the hole with tape.

What causes the pendulum to stop?

When the swing is raised and released, it will move freely back and forth due to the force of gravity on it. The swing continues moving back and forth without any extra outside help until friction (between the air and the swing and between the chains and the attachment points) slows it down and eventually stops it.

## Does length affect period of pendulum?

The period of a pendulum does not depend on the mass of the ball, but only on the length of the string. Two pendula with different masses but the same length will have the same period. Two pendula with different lengths will different periods; the pendulum with the longer string will have the longer period.

Why do shorter pendulums swing faster?

From the time period formula, time period of the pendulum is directly proportional to the square root the length of the pendulum. When the length of the string is shorter the time period of the pendulum decreases. Was this answer helpful?
