Kunzwisisa ma static uye dynamic fluids
Mufizikisi, mvura inotsanangurwa sechinhu chinogona kuyerera. Makadzidza kuti zvinhu zvatinosangana nazvo muhupenyu hwezuva nezuva zvinosanganisira zvinhu zvakasimba, mvura, uye magasi. Izwi rekuti mvura rinosanganisira mvura nemagasi, nekuti mvura yakaita semvura nemagasi akaita semhepo inogona kuyerera. Zvinhu zvakaoma zvakaita sedombo kana simbi hazvigone kuyerera saka hazvigone kuverengerwa semvura. Kuti munzwisise tsananguro iyi zviri nani, zvinobatsira kufunga nezvemimwe mienzaniso kubva muhupenyu hwezuva nezuva. Paunogeza, zvechokwadi unoda mvura. Kuti usvike padziva, mvura inoyerera kubva pachitubu kana kuti inotorwa kubva mutsime. Mvura muenzaniso mumwe wemvura. Kune mimwe mienzaniso yemvura, yakaita semafuta ekuzora, mukaka, nezvimwewo. Zvese izvi zvinonwiwa zvinogona kuverengerwa semvura nekuti zvinogona kuyerera kubva panzvimbo imwe kuenda kune imwe. Magasi zvakare mvura. Magasi anogonawo kuyerera kubva panzvimbo imwe kuenda kune imwe. Mhepo inovhuvhuta muenzaniso wemhepo inofamba kubva panzvimbo imwe kuenda kune imwe.
Kunze kwezvinhu zvakasimba, zvinwiwa, uye magasi, kune rumwe rudzi rwezvinhu zvinonzi plasma. Plasma igesi ine ionized uye inowanzonzi mamiriro echina ezvinhu . Unogona kudzidza zvakawanda nezve plasma kukoreji. Zvisinei, plasma haina kuiswa muchikamu chemvura.
Mvura Dzisingachinji uye Dzinochinja-chinja
Mvura inoyerera chinhu chakakosha muhupenyu hwedu hwezuva nezuva. Zuva rega rega, tinoifema, tinoinwa, uye tinotoyangarara kana kunyura mairi. Zuva rega rega, ndege dzinobhururuka nepakati payo, ngarava dzinoyangarara pamusoro payo, uye ngarava dzemugungwa dzinogona kuyangarara kana kudonha mairi. Mvura yatinonwa nemhepo yatinofema zvinotendererawo mumiviri yedu nguva dzose, dzimwe nguva tisingatombozvizivi.
Pakudzidza nezvemvura, tinoipatsanura kuita zvikamu zviviri: mvura inomira (fluid statics) uye mvura inomira (fluids in motion). Mumvura inomira, tinoongorora mvura inomira iri mumamiriro ekuenzana. Nokudaro, tinoongorora mvura inomira iri. Mumvura inomira, tinoongorora mvura inomira iri kufamba.
