3. * INERTIA- The tendency of a body to remain at
rest in a straight line is called inertia.
-Inertia is that property of a body due to which it
resist in its state of rest or of uniform motion.
-Mass is the measure of inertia.
-Inertia are three types:-
*Inertia of rest
*Inertia of motion
*Inertia of direction
4. Inertia of rest is the famous
demonstration of inertia,
usually involving a dining table
covered with a cloth and set
with dishes, etc. A quick pull,
and the cloth can be removed
from the table with the
settings intact and in close to
the same positions as before.
The inertia of the dishes keeps
them where they are.
5. There is a preferred motion in space known an inertial motion. Any body left to itself in space will
default to an inertial motion, which is just motion in uniform speed in a straight line.
The easiest example to visualize is a huge spaceship with the engines turned off, gliding through
space. At any point in space, many inertial motions are possible. They will be pointed in different
directions and will be at different speeds
6. Inertia of direction is a property due to which body maintains its
sense of direction.
E.g-A ball rolled on a horizontal floor continous to move in a straight
line.
7. . Application of inertia-induced acoustic excitation theory
offers a new resonant excitation source channel of acoustic
turbulence in the transonic domain of plasma flow. In bi-ion plasmas
like colloidal plasma, two well-defined transonic points exist
corresponding to the parent ion and the dust grain-associated
acoustic modes. As usual, the modified ion acoustic mode (also known
as dust ion-acoustic (DIA) wave) dynamics associated with parent ion
inertia is excitable for both nanoscale- and micronscale-sized dust
grains. It is found that the so-called (ion) acoustic mode (also
known as dust-acoustic (DA) wave) associated with nanoscale dust
grain inertia is indeed resonantly excitable through the active role
of weak but finite parent ion inertia. It is interestingly
conjectured that the same excitation physics, as in the case of
normal plasma sound mode, operates through the active inertial role
of plasma thermal species. Details of the nonlinear acoustic mode
analyses of current interest in transonic domains of such impure
plasmas in hydrodynamic flow are presented.
