Yamandla entshukumo: ingqiqo

I amandla entshukumo - kukuthi, ngokwenkcazelo, ixabiso ngokulinganayo isiqingatha ubunzima umzimba ihamba, iphindwe isikweri uqina lomzimba. Lo - ngomnye imiqathango ibalulekileyo ubucukubhede mihla. Ngokufutshane nje, ukuba amandla sesindululo, okanye umahluko phakathi amandla iyonke kunye namandla abanye. Kodwa umongo nto akujongwa ngokupheleleyo kwinzululwazi mihla.

Namandla ekinetiki (ukusuka Gr Kinema -. Movement) komzimba kwimo nokungakwazi ngu zero. Amaxesha amaninzi, eli xabiso ayithethi kuphela zinxulumene ubunzima kunye nesantya. Ngoko ke, ngokutsho definition omnye, amandla entshukumo - oku ngumsebenzi owenziwa ngesantya ethile. It ulinganiswa ziijowule.

Amandla entshukumo le nkqubo - le mali, nto leyo ngokusondeleyo enxulumene izinga nganye amanqaku ayo.

Kucingwa kwi intshukumo phambili, kwaye lwezityalo. Kwimeko yokuqala sele icacisiwe iinkcukacha ngasentla, oko - isiqingatha ubunzima bento liphindaphindwe Velocity yayo ophindwe kabini. A umzimba ukujikeleza amandla agciniweyo uchazwa umdibaniso amandla entshukumo nganye imiqulu eziziziqalelo umzimba. Okanye njengoko ixabiso mzuzu inertia liphindaphindwe kwisikweri se Velocity emboxo lahlulwe ngo ezimbini.

Thelekelela ukuba kukho nayiphi na into eqinileyo into eshukumayo emhlabeni esqwini odlula therethrough umile. Le yinto lungahlulwa-hlulwa zibe ngamasuntswana amancinci umthamo, nganye eneyazo ubunzima yayo elemental. Ezijikeleze axis eliqingqiweyo sindululo yenza umzimba phantsi ingqalelo. Enanikade ngasinye imiqulu nezakhiwo ichaza isangqa elihambisana le radius. Efanayo ngesantya emboxo ujikelezo. Kwaye ngoko ke amandla agciniweyo umzimba - idibanisa amandla entshukumo nezakhiwo zawo zonke, ngokujikeleza ezimanyeneyo mqulu. A elula ifomula - isiqingatha udibaniso isikweri uqina emboxo kunye mzuzu inertia.

Kwezinye iimeko, amandla entshukumo - le mali kunye namandla translational kunye ejikelezayo. Umzekelo, ukutyibilika phantsi ngaphandle ngokuwatshibiliza ecaleni komgca cylinder bethana. Ukuqhubela phambili, oko wenza intshukumo phambili, kodwa kwangaxeshanye ebuya kwakhona ngeenxa axis yayo.

Enye yeendima na amandla agciniweyo wokujikelezisa - lo mzuzu ye inertia, leyo kuxoxwe ngasentla. Kuxhomekeke lilonke ubunzima bomzimba, ngokunjalo ukusasazwa yayo ngokunxulumene esqwini ujikelezo. Yintoni na? It is a umlinganiselo inertia malunga esqwini sesindululo ngokunjalo kwi intshukumo inkqubela ngumlinganiselo le inertia kunobukhulu. Eli lixabiso ebaluleke kakhulu. Lo mzuzu inertia, ukuba nzima ukuba umzimba sikarhulumente ejikelezayo. Velocity emboxo ichaza isantya ngayo ihamba eqinileyo ngeenxa axis yayo. Le yunithi Rad / s. Le Velocity emboxo lulwahlulo njengokujikeleza engile ukuya ubude bexesha apho le engela eyipasile into olujikelezayo.

Theorem zamandla entshukumo kukwazi ukwakhiwa ngolu hlobo: mandla msebenzi isiphumo isicelo nomzimba ethile, kulingana utshintsho amandla agciniweyo umzimba.
