Iphuzu impahla

Kususelwa kungenzeka kwasendaweni eziphathekako ngesikhathi nendawo, e Mechanics classical, ukutadisha imithetho ukuhambisa iqala icala silula. Lesi sehlakalo ukunyakaza iphuzu impahla. umqondo lomqondo kuyizinhlayiyana aphansi Mechanics kohlaziyo wakha isendlalelo kokwethula imithetho eyisisekelo Dynamics.

iphuzu Material - into ine usayizi kuncane nesisindo sokugcina. Lo mbono okuhambelana ngokuphelele umfanekiso imvelo ngokuqhubekayo kwendaba. Ngaphambili, izazi zesayensi ziye wazama bakuchaza ngokuthi iqoqo izinhlayiya aphansi ukuthi ayakwazi ukuthuthela. Kule ndaba, iphuzu impahla e Dynamics salo sesibe nje kunesidingo sokuba theory kwaqanjwa ithuluzi.

Dynamics into esekelwe isimiso inertial. Ngokusho kwakhe, iphuzu yezinto ezibonakalayo, hhayi ukuba ngaphansi kwethonya amabutho angaphandle, igcina esimweni saso lokuphumula (noma ukufuduka) ngokuhamba kwesikhathi. Leli lungiselelo kwenziwa ngokuqinile ngokwanele.

Ngokuhambisana isimiso inertia, iphuzu impahla (mahhala) ezihambayo nombala futhi rectilinearly. Uma ucabangela icala ekhethekile lapho Isivinini zero, kungashiwo ukuthi into azigcina isimo ukuphumula. Kule ndaba, kungaba bazitshela ukuthi ithonya ibutho elithile ku lale ndaba akhuluma ngayo Simane ushintsho ijubane layo uma igijima. Umbono elula ngoba kucatshangwa ukuthi ijubane ushintsho, okuyinto has a iphuzu okokusebenza ngqo wakhona olubonisa ukuthi amandla asetshenziswa ke. Isici proportionality incipha nge okwandisa inertia.

impahla Natural amaphuzu sici usebenzisa ubukhulu inertia isilinganiso - mass. Kulokhu, umthetho eyinhloko Dynamics into kukwazi ukwakhiwa kanje: ukuze accelerations ngesikhathi ngamunye isilinganiso amandla ayisukumele into isisindo salo. Isitatimende kinematics, ngaleyo ndlela obulandela isethulo izikhulumi. IMisa, okuyinto ephawula okubakhona iphuzu ezibonakalayo, wasungula posteriori (kusukela isipiliyoni), ngenkathi khona trajectory isikhundla, ukusheshisa, isivinini wayivumela priori.

Kule ndaba, ezothando we Dynamics into baphikisa ngokuthi umkhiqizo nenqwaba into kunoma yiziphi izingxenye ukusheshisa yayo uyalingana ingxenye okuhambisanayo bebutho ayisukumele into. Uma kucatshangwa ukuthi amandla umsebenzi aziwayo isikhathi futhi isikhundla, sokunquma izixhumanisi nezinhlayiya ngokuhambisana isikhathi ezivezwa ezintathu abavamile umehluko zibalo oda yesibili ngokuphathelene nesikhathi.

Ngokuhambisana theorem owaziwa kusukela Yiqiniso sokuhlaziya zezibalo, ikhambi wathi uhlelo of zibalo is ehlukile kunqunywa izixhumanisi, nemikhiqizo yabo lokuqala ukuqala isikhathi sokuphumula. Ngamanye amazwi, lapho umbono othile ngokuya impahla kanye velocity kwayo iphuzu elithile ungakwazi ukunquma ngokunembile ubunjalo ukufuduka yayo yonke nezikhathi esizayo.

Ngenxa yalokho, kuyacaca ukuthi Dynamics classical into is ngaphakathi accordance nga ngokuphelele nesimiso Determinism ngokomzimba. Ngokusho lokhu, ukufika isimo (isikhundla) indaba ka emhlabeni kungenziwa wabikezela ngokuphelele ebukhoneni nemingcele ekutholeni isikhundla salo esikhathini esithile esedlule.

Ngenxa yokuthi ubukhulu iphuzu impahla unamandla amancane, trajectory yayo kuyoba umugqa bangazihluphi ezintathu isikhala ntathu continuum ntathu kuphela. indlela ngayinye sigaba kukhona amandla inani elithile ecacisa ukunyakaza elilandelayo kwesikhathi kuncane isikhathi.
