I-LMEC-3 Pendulum elula ene-Electric Timer

Isingeniso

Ukuhlolwa okulula kwe-pendulum kuyisilingo esidingekayo ekufundiseni okuyisisekelo kwasekolishi nasekufundiseni i-physics esikoleni esiphakathi. Esikhathini esedlule, lokhu kuhlolwa bekukhawulelwe ekulinganiseni isikhathi sokudlidliza kwebhola elincane ngaphansi kwesimo se-pendulum elula esenza cishe ukulingana kwesikhathi esilinganayo nge-engeli elincane, imvamisa kungabandakanyi ubudlelwano phakathi kwenkathi ne-angle ye-swing. Ukuze kufundwe ubudlelwano phakathi kwabo, ukukalwa ngezikhathi ezithile kufanele kwenziwe ema-angles e-swing ahlukahlukene, noma kuma-engeli amakhulu wokujikisa. Indlela yendabuko yokulinganisa umjikelezo isebenzisa isikhathi esinqunyiwe sesitophuwashi, nephutha lokulinganisa likhulu. Ukuze unciphise iphutha, kuyadingeka ukuthatha inani elijwayelekile ngemuva kokulinganiswa kwezikhathi eziningi. Ngenxa yobukhona bokudamba komoya, i-swing angle iyabola ngokwengezwa kwesikhathi, ngakho-ke akunakwenzeka ukukala ngokunembile inani elifanele lesikhathi se-swing ngaphansi kwe-angle enkulu. Ngemuva kokusebenzisa i-switch switch sensor ye-switch kanye ne-timer ye-elekthronikhi ukubona isikhathi esizenzakalelayo, isikhathi se-pendulum elula engela enkulu singalinganiswa ngokunembile kumijikelezo embalwa emfushane yokudlidliza, ukuze ithonya lomoya oshisayo engxenyeni ye-swing linganakwa , futhi ukuhlolwa kobudlelwano phakathi kwenkathi ne-angle ye-swing kungenziwa ngokushelela. Ngemuva kokutholwa kobudlelwano phakathi kwenkathi ne-angle ye-swing, isikhathi sokudlidliza esinama-angle amancane kakhulu we-swing singalinganiswa ngokunembile ngokukhipha i-angle ye-zero jika, ukuze ukushesha kwamandla adonsela phansi kukalwe kahle.

Ukuhlolwa

1. Linganisa isikhathi sokujija ngobude bezintambo obungaguquki, bese ubale ukushesha kwamandla adonsela phansi.

2. Linganisa isikhathi sokujikisa ngokuhlukahluka kobude bezintambo, bese ubale ukushesha okuhambisanayo kwamandla adonsela phansi.

3. Qinisekisa ukuthi isikhathi se-pendulum silingana nesikwele sobude bezintambo.

4. Linganisa isikhathi sokushintshashintsha ngokuhlukahluka kwe-angle yokuqala, bese ubale ukushesha kwamandla adonsela phansi.

5.Sebenzisa indlela ye-extrapolation ukuthola ukushesha okunembile kwamandla adonsela phansi engxenyeni encane yokushwibeka.

6. Fundisisa ithonya lomphumela ongahambisani nomugqa ngaphansi kwama-engeli amakhulu wokujikisa.
