Isantya Instant: ingqiqo, ifomula ukubala, izincomo akumfumana

Ngesantya physics kuthetha ngesantya uyivulele kwento (material point) kwisithuba. Le Ixabiso lingaba ezahlukeneyo: a yomgama, emboxo, aphakathi, indawo kunye superluminal. Phakathi zonke iintlobo ezikhoyo ongena kwaye uqina lwephanyazo ngokunjalo. Loluphi uhlobo ixabiso, yintoni na ifomula bayo, bungakanani amanyathelo ziyafuneka ukubala nje - ukuba nje kwaye kuya kuxoxwa ngazo kwinqaku lethu.

isantya Instant: kakuhle isigama

Ukuze ufumane inkcazelo engakumbi ukujonga ukuba izixa-isantya intshukumo injongosenzi kumgca othe tye, kwaziwa kubafundi bezikolo zaseprayimari: umgama ngokwaneleyo ayehamba bahlulwe ixesha isetyenziswe ulolo hlobo. Nangona kunjalo, kubalulekile ukukhumbula ukuba umphumo efunyenwe ngale ndlela, ibonisa ixabiso. Ukuba into ihamba bengaphuhlanga ngokulinganayo, ukuba iindawo ezithile ngesantya umdla umendo ziyahluka kakhulu. Ngoko ke ngamanye amaxesha kufuneka, ezifana ixabiso Velocity nje ngephanyazo. Inika isalathisi se kwisantya ukuhamba yencopho eziphathekayo kuyo nayiphi na imiqondiso yendlela elinikiweyo.

Isantya leso yokubala ifomula

Le parameter ilingana kumda (nani lezithuba libonisiweyo, lim olufinyeziweyo) ukuhanjiswa (umahluko zilungelelanise) ixesha lekhefu apho kwenzeka utshintsho, ngokuxhomekeka ekubeni ixesha lidla ukufikelela zero. Le nkcazelo angabhalwa indlela zilandelayo:

v = ii / Δt ukuba Δt → 0 okanye ngoko v = lim _{Δt → 0} (ii / Δt)

Qaphela ukuba uqina lwephanyazo ke ubuninzi kumda wesangqa. Ukuba isindululo kuba kumgca othe tye, itshintsha kuphela umthamo kunye nolwalathiso kuhlala rhoqo. Kungenjalo, le Velocity kumda wesangqa lwephanyazo wayalela tangentially ngokuphathelele kwindlela intshukumo kwingongoma nganye ingqalelo. Ngayiphi ingqiqo le salathisi? Isantya Instant kwenza kube lula ukufumanisa oko kuya kwenza intshukumo into ngeyunithi nganye ixesha, ukuba ingqalelo ukususela ekudalweni ebuya ngokufanayo kumgca othe ngqo.

Tips

Kwimeko isindululo efanayo akukho nzima, kufuneka nje ukufumana umlinganiselo umgama ukuya kwixesha apho waxhomekeka ukuzoyisa. Kulo mzekelo, avareji kunye lwephanyazo Velocity yequmrhu uyalingana. Ukuba isindululo akwenzeki njalo, ngoko kule meko ukwazi kukukhawuleziswa kwaye isigqibo uqina lwephanyazo nangaliphi enikwe ixesha. Xa intshukumo nkqo kufuneka athathe ingqalelo impembelelo yokunyusa omxhuzulane. Isantya isithuthi leso kungenziwa imiselwe radar okanye isantya. Kufuneka kukhunjulwe ukuba intshukumo kwezinye amacandelo indlela ingathatha engenaxabiso. Ukuze ufumane ukukhawulezisa, unako ukusebenzisa i accelerometer ukwenza nawuphi na umsebenzi intshukumo kwaye usebenzise v ifomula = v0 + a • t. Ukuba intshukumo iqala ukuphumla, ngoko v0 = 0. Ezi zibalo kufuneka ithathele ingqalelo into yokuba umzimba (umyinge nciphisa) elekhtrons Ixabiso lunikezelo iza kuba ngumqondiso "thabatha". Ukuba into yenza ukuwa, isantya lwephanyazo of ukubana yayo ibalwa yi v ifomula = g • t. Kulo mzekelo, i uqina yokuqala lingana kwakhona 0.
