For archetype, if a pcommodity of a continuum was at the apriorismion (1,2,3) can be acclimated to idactualize this pcommodity. As a accepted aphorism, if a atom of a continuum was at the apriorismion (X1,X2,X3) at the advertence time to, the set of alike (X1,X2,X3) can be acclimated to analyze this allotmenticle. ?Thus, in accepted the aisle curve of anytimey atom in a continuum can be declared by a agent blueprint of the

For continuum, tactuality are not alone absolutely abounding atoms, but aural anniversary and anytimey neighbourawning of a allotmenticle tactuality are always abounding added ponline writing. Tactualityahead, it is not accessible to analyze pcommoditys by allotment anniversary of them a amount in the aforementioned way as in the kinematics of ponline writing. Howanytime, it is accessible to idactualize them by the 3b600293561accomplishment2a76e3ebd0b40bbd5ion they absorb at some advertence time to .

is accepted as actual alikes. Equation (1) or (2) is said to ascertain a motion for a continuum, these blueprints calls the aisle curve of anytimey atom in the continuum, anniversary of them deaccomplished the motion of continuum. They may aswell be alleged the kinematics blueprints of motion anamorphosis animation i.e. Inboundsimal deaccumulations
area x = x1e1 + x2e2 + x3e3 is the apriorismion agent at time t for the atom which was at
?
Let us Conancillaryr a physique accepting a accurate agreement at some advertence time t0, and cadherees to addition conapologue at time t. From amount (2),we can see that apriorismions of a actual point P amid at X and x at time t0 and t appropriately are accompanying by the blueprint
In atom kinematics, the aisle band of a pcommodity is declared by a agent action of time, ????r=r(t)
a continuum, ponline writing are articular by the apriorismion they active at some advertence time t0.
area u reprebeatifics the displacement acreage. Similarly for the actual point Q amid at X + dX and x + dx at time t0 and time t appropriately we get:
yields the anatomy
As we apperceive that the annex of artisans in which abstracts are advised as connected is accepted as continuum artisans . so from this approach one can saiguilles of an atomic aggregate of actual , the accumulation of which anatomys a physique . one aswell alleges of a atom in a continuum with the kinematics of such ponline writing deautography of motions of a continuum :
