Kuwanda Kwezvinhu Zvinoenderana Nezvinodiwa, Kukurumidza, uye Simba
Pendauluan
Dzidziso yakakosha ye relativity, yakagadzirwa naAlbert Einstein muna 1905, yakachinja zvikuru manzwisisiro atinoita pfungwa dzehukuru, simba, uye simba. Mukati mehurongwa hwe special relativity, pfungwa idzi hadzisisiri dzakakwana, sezviri muNewtonian physics, asi dzinoenderana nekumhanya kwechinhu kana tichienzanisa nemuoni. Chinyorwa chino chichakurukura zvakadzama pfungwa dze relativity dzehukuru, simba, uye simba, uye zvadzinoreva kufizikisi yemazuva ano.
Misa yeKuwirirana Kwezvinhu
Mufizikisi yekare, huremu hunoonekwa sehunhu husingachinji hwechinhu, husingatsamiri pakumhanya kwacho. Zvisinei, muhukama hwakakosha, huremu hwechinhu hunoenderana nekumhanya kwacho kana tichienzanisa nemuoni.
Misa Inoenderana Nezvinodiwa Nevamwe vs. Misa Isingachinji
– Kuwanda Kusingachinji (Kuwanda Kwekuzorora, \(m_0\)): Kuwanda Kusingachinji ihuremu hunoyerwa nemucherechedzi achifamba nechinhu, ndiko kuti, kana chinhu chacho chakamira kana tichienzanisa nemucherechedzi. Kuwanda Kusingachinji ihuremu husingachinji uye hahuchinji pasinei nekumhanya kwechinhu chacho.
– Relativistic Mass (\(m\)): Relativistic mass ihuremu hunoenderana nekumhanya kwechinhu kana tichienzanisa nemuoni. Huremu uhwu hunowedzera sezvo kumhanya kwechinhu kuchiwedzera uye hunogona kuratidzwa ne equation:
\[ m = \frac{m_0}{\sqrt{1 – \frac{v^2}{c^2}}} \]
Di mana:
– \( m \) ihuwandu hwezvinhu hunotsamira pamaonero emunhu.
– \( m_0 \) ndiyo huwandu hwese (husingachinji).
– \( v \) ndiyo kumhanya kwechinhu.
– \( c \) ndiko kumhanya kwechiedza.
Huremu hwechinhu hunowedzera pasina muganho sezvo kumhanya kwechinhu kuchisvika pakumhanya kwechiedza, zvichireva kuti chinhu chine huremu hwekuzorora hachigone kusvika kana kupfuura kumhanya kwechiedza nekuti chinoda simba risingaperi.
Kukurumidza Kuchinja Kwemaonero Emunhu
Momentum muNewtonian physics inotsanangurwa sechibereko chehukuru hwechinhu uye kumhanya kwacho (\(p = mv\)). Mukuenzanisa kwakakosha, tsananguro iyi inowedzerwa kuti isanganise mhedzisiro yekuenzanisa.
Tsanangudzo yeRelativistic Momentum
Simba rekuchinja-chinja (\( p \)) rinotsanangurwa se:
\[ p = \gamma m_0 v \]
Di mana:
– \( p \) ipfungwa yekuchinja-chinja mamiriro ezvinhu.
– \( \gamma \) ndicho chinhu chinonzi Lorentz, icho chinotsanangurwa se:
\[ \gamma = \frac{1}{\sqrt{1 – \frac{v^2}{c^2}}} \]
– \( m_0 \) ndiyo huwandu hwese hunosara.
– \( v \) ndiyo kumhanya kwechinhu.
Chinhu chinonzi Lorentz factor (\( \gamma \)) chinowedzera nekumhanya kwechinhu uye chinosvika pakusingapere sezvo kumhanya kwacho kuchisvika pakumhanya kwechiedza. Nekuda kweizvozvo, simba re relativistic rinowedzerawo zvakanyanya pakumhanya kwakakwirira.
Simba Rinopindirana Nezvimwe Zvinhu
Pfungwa yesimba mu special relativity inosanganisira simba rekinetic uye simba rekuzorora (simba guru) rechinhu. Simba rose (\(E\)) rechinhu mu special relativity musanganiswa wezvikamu zviviri izvi.
Simba Rese uye Kinetic Energy
Simba rose mu special relativity rinotsanangurwa se:
\[ E = \gamma m_0 c^2 \]
Di mana:
– \( E \) isimba rose.
– \( \gamma \) ndicho chinhu chinonzi Lorentz.
– \( m_0 \) ndiyo huwandu hwese hunosara.
– \( c \) ndiko kumhanya kwechiedza.
Simba rose rinosanganisira simba rekinetic uye simba rekuzorora. Simba rekinetic relativistic (\( E_k \)) rinogona kuwanikwa nekubvisa simba rasara kubva musimba rose:
\[ E_k = E – m_0 c^2 \]
\[ E_k = (\ gamma – 1) m_0 c^2 \]
Pakumhanya kwakaderera (\( v \ll c \)), simba rekinetic rinoenderana nerelativistic rinosvika pasimba rekinetic rekare (\( \frac{1}{2} m_0 v^2 \)).
Equation yeMasimba-Energy
Imwe yemhedzisiro inozivikanwa zvikuru ye special relativity i equation ye mass-energy, iyo inoratidza hukama huripo pakati pe mass nesimba:
\[ E = mc^2 \]
Iyi equation inoratidza kuti huremu hunogona kushandurwa kuita simba uye zvinopesana. Iyi ndiyo nheyo iri pasi pemaitiro enyukireya uye zviitiko zvakaita sekuparadzana kweparticle-antiparticle, uko particles neantiparticles zvinonyangarika uye simba razvo rinoburitswa semaphotons (zvimedu zvechiedza).
Zvinorehwa uye Mashandisirwo eSpecial Relativity
Fizikisi yezvikamu
Mufizikisi yezvikamu, hunyanzvi hwekubatanidza zvinhu hunokosha pakunzwisisa maitiro ezvikamu zvepasi peatomu pakumhanya kwakanyanya. Zvikamu zvinofamba pedyo nekumhanya kwechiedza, zvakaita semaerekitironi ari muzvigadziriso zvezvikamu, zvinoratidza mhedzisiro yakakosha yekubatanidza zvinhu. Equation yesimba-simba inotibvumira kunzwisisa maitiro akadai sekuora kwemwaranzi uye kubatanidzwa kwenyukireya.
Zvemuchadenga
Special relativity ine basawo mu cosmology, kudzidza mavambo uye chimiro chemuchadenga. Semuenzaniso, cosmic microwave background radiation, yakasara yeBig Bang, inonzwisiswa zviri nani mukati mehurongwa hwe special relativity. Uyezve, special relativity ndiyo hwaro hwe general relativity, iyo inoshandiswa kutsanangura gravity uye kushanduka kwemuchadenga.
Tekinoroji Yemazuva Ano
Matekinoroji mazhinji emazuva ano anovimba nemisimboti yehukama hwakakosha. Semuenzaniso, masisitimu eGPS anoda kugadziriswa kwehukama kuti ape nzvimbo chaiyo. Masatellite eGPS anofamba nekumhanya kwakanyanya kana tichienzanisa nepamusoro peNyika, uye musiyano wenguva unokonzerwa nemigumisiro yehukama unofanira kuverengerwa.
Simba reNyukireya
Simba renyukireya, mune zvese zviri zviviri muzvishandiso zvenyukireya uye muzvombo zvenyukireya, ibasa rakananga reEinstein's mass-energy equation. Muzvishandiso zvenyukireya, huwandu hushoma hwehuremu hunoshandurwa kuita huwandu hwakawanda hwesimba, hunogadzirwa nekubatana kana kuti fission reactions.
Mhedziso
Dzidziso yaAlbert Einstein ye relativity yakaunza pfungwa dze relativistic mass, momentum, uye energy, zvichichinja kunzwisisa kwedu fizikisi. Relativistic mass inowedzera nekukurumidza, relativistic momentum inoratidza maitiro asina kurongeka nekumhanya kwakanyanya, uye total energy inosanganisira kinetic uye rest energy.
Equation yesimba guru \(E = mc^2 \) yakagadzira nzira yekushandisa tekinoroji nesainzi, kusanganisira fizikisi yezvipenyu, cosmology, uye simba renyukireya. Dzidziso yakakosha yehukama haingotsananguri zviitiko zvisingagone kutsanangurwa nefizikisi yekare asiwo inopa hwaro hwedzidziso yakajairika yehukama uye kunzwisisa kwakadzama kwezvisikwa.
Saka, kunzwisisa kwehukuru, simba, uye relativistic kwakakosha kune chero nyanzvi yefizikisi uye musayendisiti anoda kuongorora miganhu yeruzivo rwevanhu nezvechisiko chose. Dzidziso yakakosha ye relativity inoramba iri imwe yebudiriro huru munhoroondo yesainzi, ichiratidza simba uye runako rwemasvomhu mukutsanangura zviitiko zvechisikigo.
