Kudla ngokuthiwa imbumbulu ifana nelori. Kodwa ngaba oku kuyinyaniso? Ukuqonda impendulo, umntu kufuneka aqonde kuqala umfutho. Isantya silinganisa ukungazinzi kwento okanye ukuxhathisa ukuguquka kwentshukumo. Ilingana nobunzima bento ephindwe ngesantya sayo. Okukhona into inzima, kokukhona ishukumayo kwaye kokukhona ikhula ngamandla.
Unale nto engqondweni, kulula ukubona ukuba kutheni imbumbulu kunye nelori zinokuba nomfutho ofanayo. Imbumbulu isenokukhaphukhaphu kodwa inokuhamba ngesantya esiphezulu kakhulu. Ngokwahlukileyo, iilori zinokuba nzima kakhulu kuneembumbulu kodwa zihamba ngesantya esisezantsi. Logama nje ezi zinto zimbini zinesantya esifanayo sobunzima besantya, ziya kuba nomfutho ofanayo.
Nangona kunjalo, njengoko umfutho bubuninzi be-vector, kuyafuneka ukuba kuthathelwe ingqalelo indlela yokuhamba. Imbumbulu kunye nelori zinokuba namandla afanayo. Nangona kunjalo, umfutho wabo uya kuncipha ukuba bahamba kumacala ahlukeneyo. Kule meko, izinto ezimbini ziya kuba nomfutho we-zero. Kwakhona kuyafaneleka ukuba uqaphele ukuba ukukhawuleza kuhluke kumandla e-kinetic.
Ngoko ke, impendulo emfutshane kulo mbuzo nguewe, imbumbulu inokuba namandla afanayo nelori xa inikwe ukuba inobunzima obufanayo besantya.

Ngaba imoto kunye nelori zinokukhawuleza okufanayo?
Ewe, banako. Isantya sento silingana nobunzima bayo obuphindwe ngesantya sayo. Logama nje imoto kunye nelori zinesantya esifanayo sobunzima besantya, ziya kuba nomfutho ofanayo.
Nangona kunjalo, kunokwenzeka ukuba imoto kunye nelori zibe nesantya esahlukileyo kubomi bokwenyani. Iimoto zihlala zincinci kuneelori kwaye zinobunzima obuncinci. Ngapha koko, iilori zihlala zihamba ngesantya esiphezulu kuneemoto. Ngenxa yoko, kunokwenzeka ukuba ilori ibe nesantya esimangalisayo kunemoto.
Kwenzeka ntoni ukuba izinto ezimbini zinesantya esifanayo?
Xa izinto ezimbini zinomfutho ofanayo, zihamba kwicala elinye ngesantya esilinganayo okanye kumacala achaseneyo anezantya ezifanayo. Kuyo nayiphi na imeko, amandla azo zombini izinto anokungavisisani enye kwenye, okukhokelela kwintshukumo edityanisiweyo ye-zero.
Ingaba ilori nesithuthuthu zinokuba nomfutho ofanayo?
Ewe, banako. Isantya sento silingana nobunzima bayo obuphindwe ngesantya sayo. Ukuba ilori kunye nesithuthuthu zinesantya esifanayo sobunzima besantya, ziya kuba nomfutho ofanayo.
Nangona kunjalo, kwiimeko ezininzi, kunokwenzeka ukuba ilori kunye nesithuthuthu zibe nesantya esahlukileyo. Iilori zidla ngokuba nkulu kwaye zinzima kunezithuthuthu, ezidla ngokuhamba ngokukhawuleza. Ngenxa yoko, kunokwenzeka ukuba isithuthuthu sibe nesantya esimangalisayo kunelori.
Ngaba izinto ezimbini ezinoMvuzo ofanayo zinaMandla eKinetic afanayo?
Izinto ezimbini ezinesantya esifanayo azikwazi ukuba namandla ekinetic afanayo. Amandla eKinetic alingana nesiqingatha sobunzima bento ephindwe ngesantya esiphindwe kabini. Kuba umfutho ulingana nesantya samaxesha obunzima, izinto ezimbini ezinesantya esifanayo zinokuba namandla ahlukeneyo ekinetic. Umzekelo, into enzima kunye nekhaphukhaphu inokuba nesantya esifanayo ukuba into enzima ihamba kancinci kwaye into elula ihamba ngokukhawuleza. Kule meko, into elula iya kuba namandla amaninzi e-kinetic kunento enzima.
Ingaba ibhayisekile yomdyarho ingaba nako njani umfutho ofanayo nowelori yokulanda?
Isantya somgca sibhekiselele kwisantya kumgca othe ngqo. Ilingana nobunzima bento ephindwe ngesantya sayo. Ke ngoko, ibhayisekile yomdyarho kunye nelori yemoto inokuba nesantya esifanayo kunye nesantya sobunzima besantya.
Nangona kunjalo, kwiimeko ezininzi, kunokwenzeka ukuba ibhayisekile yomdyarho kunye nelori ibe nesantya esahlukileyo somgca. Iibhayisekile zikhaphukhaphu kakhulu kuneelori kwaye zinobunzima obuncinci. Ngapha koko, iilori zihlala zihamba ngesantya esiphezulu kuneebhayisekile. Ngenxa yoko, kunokwenzeka ukuba ilori ibe nesantya esikhulu somgca kunebhayisekile.
Ngaba into eneZero Momentum inaMandla eKinetic?
Into ene-zero momentum ayinakuba namandla ekinetic. Amandla eKinetic alingana nesiqingatha sobunzima bento ephindwe ngesantya esiphindwe kabini. Kuba umfutho ulingana nesantya samaxesha obunzima, into enesantya esinguziro ayinakuba namandla ekinetic angengo-zero.
Ngaba iNto ekuphumleni inokuba nesantya?
Hayi, into ephumle ayinako ukuba namandla. Isantya silingana nobunzima bento obuphindwe ngesantya sayo. Ekubeni isantya singumlinganiselo wesantya, into ephumleyo inesantya esinguziro kwaye, ngenxa yoko, ayinakuba nesantya. Into inokuba namandla kuphela xa ishukuma.
Ingaba iMisa iyichaphazela njani i-Linear Momentum?
Ubunzima ngumlinganiselo wokungaguquguquki kwento okanye ukuxhathisa kwayo utshintsho kwisantya. Isantya somgca silingana nobunzima bento ephinda-phindwe ngesantya sayo. Ngoko ke, okukhona ubukhulu bento bukhulu, kokukhona bukhulu umgama wayo womda. Ngokuchaseneyo, okukhona iyinto encinci ukuba inkulu, kokukhona umgama wayo uyancipha.
Isantya siyichaphazela njani i-Linear Momentum?
Isantya ngumlinganiselo wesantya kunye nesalathiso sento. Isantya somgca silingana nobunzima bento ephinda-phindwe ngesantya sayo. Ngoko ke, okukhona isantya sento sikhulu, kokukhona sikhulu isantya somgca. Ngokuchaseneyo, okukhona isezantsi isantya sento, kokukhona isantya sisezantsi somgca.
isiphelo
Ukuqukumbela, imbumbulu inokuba namandla afanayo nelori. Nangona kunjalo, imbumbulu kunye nelori iya kuba nesantya esahlukileyo kwiimeko ezininzi. Iilori zihlala zinkulu kwaye zinzima kuneembumbulu kwaye zihlala zihamba ngokukhawuleza. Ngenxa yoko, kunokwenzeka ukuba ilori ibe nesantya esimangalisayo kunembumbulu.
