A swing is a pendulum and the frequency or period of oscillation is determined by the length of the string. The period of oscillation is independent of the weight of the bob (or person sitting on the swing if their centre of gravity does not change the effective length of the pendulum swing/swing chain) and independent of the amplitude of the swing.
Incorrect period of pushes don't generate amplitude in the swing. I think they would just cancel out and the swing would slow down by means of friction and air resistance until it stops. Incorrect period of pushes would not start the swing to move once it had stopped.
Hi Norbu,
This is fun, and we're almost there ;).
The frequency of the swing is not just determined by the length of the string, but the power also, i.e. the harder the push, the higher the frequency. However, if the swing were allowed to swing at it's natural frequency, then you are right then the parameters are mass and length of string.
If a swing had a set frequency, then it was pushed at a different frequency the resultant frequency would be the product of the mix of frequencies, i.e. similar to a hetrodyne used in radio mixing.
Also in the free swing scenario it's not just the air and mechanical friction that would determine the total swinging time, it would also be determined by the child's attention span :p.

I use crystals, flower remedies and sound and reiki when I heal, so I do believe that the body resonates. We have vibrations that can be balanced by healing. Some of us are drawn to the mineral kingdom, plant kingdom, or sound and I think this all depends on our vibration and what we draw to us. I won't go into the seven rays as we all have predominant rays.
My strongest resonance is with the plant kingdom, in all of their healing forms whether its sitting in the garden, doing some aromatherapy with essences or using flower remedies.
I am drawn to radionics or psionics which is a system of healing which works on the principle of resonance and uses a 'witness' as a focal point for the healer to tune into. I've only tried this out at a MBS fair and the results seemed pretty accurate to me.
I think it would help if you gave us some idea of your view of body resonance and its use in therapy.

Saw an interesting demonstration of resonance on TV a while back. A chap was touring the far East and interviewing martial arts exponents. An expert from Japan spoke about the shout that proceeds an action. The specific martial art that he practiced, used the shout to disable an opponent. He demonstrated this. His attacker just collapsed, when shouted at. The explanation given was that the shout was at the same or multi frequency as water. As the human body is largely composed of water the effect was to disrupt the muscular state of the opponent's body causing him to collapse. It took about 3 minutes for the opponent to recover. 😮
period of attention span
The frequency of the swing is not just determined by the length of the string, but the power also, i.e. the harder the push, the higher the frequency.
Yes, I guess when there is a force applied in phase the velocity increases over the arc that the force is applied...
However, if the swing were allowed to swing at it's natural frequency, then you are right then the parameters are mass and length of string.
It's "natural" frequency is the same irrespective of the distance of the arc travelled and the terminal velocity of the bob i.e. in a state of equilibrium there is no change in period.
I don't know about a child's attention span, I'm beginning to worry about mine!:eek:

Does anyone have any thoughts on what is body resonance and its use in therapy.
I believe resonance as a healing modality has yet to be fully explored. As all atoms vibrate, then so does everything, even though we may be unaware of it. Hence, people can feel the energies in crystals and can dowse for water, etc.
MRI scans are an example of using resonance as a diagnostic tool.
There are also bio-resonance machines which pick up irregularities in various parts of the body and will usually suggest foods or supplements that may help restore the body's balance, others can be programmed to counter the disruptive energies to 'knock them out', particularly against unfriendly bacteria - see scommstech's interesting post below - though more permanently. These machines are expensive though. I have tried them and found them very helpful.
Conventional medicine is very sceptical - probably because they don't fit their modalities and they haven't been adequately 'scientifically tested' in the required 'double-blind, placebo-controlled' methods on thousands of people, just as they are trying to say that using vitamin, mineral and herbal supplements now need to be tested this way. Unfortunately very little testing is that good, and ofen the use of medication can disrupt the body's sensitive harmonic balance by altering the chemical balance. And even so called scientific tests on new drugs can be vastly flawed - see Merck's Vioxx catastrophe.
We have of course homeopathic remedies and meridian energy treatments which are using this field very usefully.
Resonance healing is a vast almost unexplored field that needs intense investigation in order to create a whole new healing modality to reduce our reliance on pharmaceuticals and surgical intervention. The medical industry will probably not be interested however.
