GAME #1 |
Hello physicists. Lets play a game....
There is a question below....for which two supposed answers follow.
________________________________________________________________________________
Q: Why does a normal person scream, when introduced to sudden physical
pain (preferably sharp)? Does screaming help create a difference in the
pain perception even marginally?
A:-
For instance, let us assume that you have a vessel of boiling water(say
400k). You insert your finger into the hot water. As the kinetic energy of the molecules inside the vessel is very high, the energy gets transferred to your finger as the molecules collide on your finger. Now, assuming that the energy gained by your body in this process is not negligible w.r.t the energy already contained in our body, the newly acquired energy will disturb the body's Energy-stability equilibrium, causing the body's stability to decrease(as we know stability is inversely proportional to energy). To compensate for the instantaneous loss of stability, the body has to engage a mechanism through which it can *quickly* lose energy. And that mechanism, is nothing but the release of energy to the air molecules around our voice box which is termed as 'screaming'.
The loudness of the scream will depend on the energy gained as well as
the time taken for the increase in the energy according to the
following expression:-
loudness of scream = (k*Energy gained)/(time taken) ; Where 'k' is a
constant.
(The practical limitations of the expression are that the 'Energy
gained' should'nt be too large or too less. Too large will be fatal and
too less will be neglected by the body.)
Therefore, it can be concluded that screaming can help create a
difference in pain-perception (marginally) by quickly regaining our
stability.
NOTE : This is just the "principle" of the pain-scream phenomenon, the
mechanics have not been discussed.
______________________________________________________________________________
B:-
The energy supplied to our body directly from any external source
does'nt add up to the energy already present in our body in the form of
glucose. The acquired energy cannot navigate in our body. Instead it is
simply used up for the defrormation of the skin cells in contact.
Sensory cells (receptors) in the stimulated body part send signals to
the spinal cord along a sensory nerve cell. Within the spine a reflex
arc switches the signals straight back to the muscles of the effectors
via an intermediate nerve cell and then a motor nerve cell; contraction
of the leg occurs, and the muscle contracts (the arm or leg jerks
upwards).
While 'screaming' is just a kind of involuntary action which can be
suppressed by will. The main purpose being a cry for help. The energy
released by this action is so trivial that it is almost negligible.
Therefore it can be concluded that screaming is unrelated with the
energy gained and it does'nt help reduce the pain experienced by the
victim.
