Pfuma pfungwa

Inobva mukana localization zvinhu mumuviri nguva uye nzvimbo, mune dzenhoroondo hurongwa, kudzidza mitemo vanotama kunotanga nyore chaizvo kana. Chiitiko ichi ndicho inofamba ane zvinhu pfungwa. Conceptual pfungwa chepuraimari PARTICIPLE Analytical hurongwa anoumba mabviro kuti mharidzo mitemo inokosha simba.

Material pfungwa - chinhu kuti ane kamwoyo kukura uye yokupedzisira uremu. Pfungwa iyi zvachose unoenderana mufananidzo discrete nehunhu nyaya. Kare, yefizikisi akaedza kutsanangura rive kutaridza zvokutanga inoramba kuti vanokwanisa kuenda. Panyaya iyi, zvinhu muupenyu emuchina ayo rava zvakakodzera kuti yokungotaura constructs chokushandisa.

The simba pamusoro chinhu inobva inertial musimboti. Maererano naye, zvinhu pfungwa, kwete ari pasi pokudzora nechitarisiko ehondo, anoramba ayo ezvinhu zororo (kana misha) pamusoro nguva. Urongwa uhwu zvinoitwa zvachose zvakakwana.

Maererano nheyo inertia, zvinhu pfungwa (vakasununguka) uchifamba noruvara uye rectilinearly. Tichitarisa nyaya inokosha umo velocity iri razero, zvinganzi kuti chinhu anoramba mamiriro kuzorora. Panyaya iyi, unogona vaifungidzira kuti pokudzora imwe simba panyaya iri kukurukurwa Inongovawo shanduko racho nokukurumidza. The nyore ndeyokuti nokufungidzira kuti kumhanya shanduko, ine zvinhu pfungwa iri Proportional kuti chinoratidza simba anokonzerwa pariri zvakananga. The proportionality chinhu shoma kuwedzera inertia.

Natural zvinhu ndiwo maitiro pfungwa kushandisa kwakakura inertia reshiyo - guru. Panyaya iyi, chikuru nomurayiro simba ari chinhu chinogona akagadzira sezvinotevera: kuti accelerations nechimwe nguva ndiyo nhamba simba kuita pamusoro chinhu wayo vakawanda. Mashoko kinematics, saka inotanga mharidzo wevakurukuri. Misa, iyo inechirevo rinomutsa kwemashoko pfungwa, ari akatanga posteriori (kubva ruzivo), apo paine trajectory chinzvimbo, kumhanyisa, kukurumidza wakatendera priori.

Panyaya iyi, mukana wokuti vanhu vanga ari simba pamusoro chinhu nharo kuti zvibereko vazhinji chinhu mumwe zvakamisa hurongwa hwayo kumhanyisa akaenzana runoenzanirana chezvinonhuwira simba kuita pamusoro chinhu. Vachifunga kuti simba iri kuvazivisa kushanda nguva uye nzvimbo, nokuti Pakusarudza Coordonatele ane PARTICIPLE maererano nguva zvinoberekwa matatu vanhuwo differential equations chechipiri kuti panyaya nguva.

Maererano inozivikanwa theorem no kubva kosi kuti akarongeka pachisara mushonga kuti akati ezvinhu equations iri inonanga pakutsvaga Coordonatele, uye vokutanga nomukaka zvavo kutanga nguva penguva. Nemamwe mashoko, kana imwe nzvimbo tichitarisa zvinhu wayo velocity pane imwe nguva anogona zvakarurama kuona hunhu waro misha yavo yose ramangwana nguva.

Somugumisiro, zviri pachena kuti dzenhoroondo rinomutsa ari chinhu chiri kwakakwana maererano nenhungamiro muviri mupi werutemo. Maererano neizvi, kuuya mamiriro (nzvimbo) mashoko kwenyika kunogona rakafanotaura zvakakwana pamberi parameters kuziva nzvimbo yayo panguva imwe yapfuura nguva.

Nokuti kuti ukuru zvinhu pfungwa akatosimba duku, ayo trajectory ichava mutsetse achitora zvitatu ndeiya yakaita nzvimbo chete ndeiya yakaita continuum. nzira nechimwe chikamu pane simba ukoshi chaiyo inotevera kufamba kamwoyo kwenguva.
