1. Imoto ezungeza ijika eligobile. Iyini i-engeli yomgwaqo onejika elingamamitha angu-60 elinejubane lomklamo elingama-20 m/s? Ake sithi ayikho friction phakathi kwemoto nomgwaqo.
Isixazululo
N= I-N sin θ = ingxenye evundlile yamandla avamile
N cos θ = ingxenye eqondile yamandla avamile
w = mg = isisindo semoto
Umgwaqo wenzelwe ukuba uvalwe ukuze kuqedwe ukuncika ekungqubuzaneni.
Amandla aphelele avundlile, ingxenye evundlile yamandla avamile ( N sin θ) , iyadingeka ukuze imoto iqhubeke ihamba ngendilinga ezungeze ijika.
Sikhetha i-x-axis njengevundlile kanye ne-y-axis njengevundlile, ukuze ukusheshisa okuphakathi nendawo,R, isendleleni evundlile. Endaweni evundlile, amandla kuphela ingxenye evundlile yamandla avamile (Isono se-N θ), edingekayo ukukhiqiza ukusheshisa okuphakathi. Isono se-N θ = amandla centripetal.
Sebenzisa umthetho kaNewton wokunyakaza ohlangothini oluqondile:

Sebenzisa umthetho kaNewton wokunyakaza ohlangothini oluvundlile:
Faka u- N esilinganisweni 1 ku-N esilinganisweni 2 :
[wpdm_package id='497′]
- Isisindo kanye nesisindo
- amandla ajwayelekile
- Umthetho wesibili wokunyakaza kukaNewton
- Amandla okungqubuzana
- Ukunyakaza endaweni evundlile ngaphandle kwamandla okungqubuzana
- Ukunyakaza kwemizimba emibili ngokusheshisa okufanayo endaweni evundlile eqinile ngamandla okungqubuzana
- Ukunyakaza endizeni ethambekele ngaphandle kwamandla okungqubuzana
- Ukunyakaza endizeni ethambekele emangelengele ngamandla okungqubuzana
- Ukunyakaza e-lifti
- Ukunyakaza kwemizimba kuxhunywe ngezintambo nama-pulleys
- Imizimba emibili enesilinganiso esifanayo sokusheshisa
- Ukuzungeza ijika eliyisicaba - amandla okunyakaza okujikelezayo
- Ukuzungeza ijika eligobile - amandla okunyakaza okujikelezayo
- Ukunyakaza okufanayo kumbuthano ovundlile
- Amandla aphakathi ahambisanayo ajikelezayo
