Imvamisa yokujika kwe-pendulum:
Imvamisa yinani lokudlidliza okwenzeka ngomzuzwana owodwa, kuyilapho isikhathi singumzuzu odingekayo ukwenza ukudlidliza okukodwa.
I-pendulum yenza ukudlidliza okukodwa uma isuka ku-A iye ku-B iye ku-C bese ibuyela ku-B bese ibuyela ku-A (A – B – C – B – A).
Kusuka ku-A kuya ku-C = ukudlidliza okungu-1/2, lapho isikhathi esidingekayo ukwenza ukudlidliza okungu-1/2 kuyimizuzwana engu-0,2.
Isikhathi esidingekayo ukuqeda ukudlidliza okukodwa yimizuzwana emi-2 x 0,2 = imizuzwana engu-0,4. Ngakho-ke isikhathi sokudlidliza kwe-pendulum = T = imizuzwana engu-0,4.
Imvamisa ye-pendulum = f = 1/T = 1/0,4 = 2,5 Hertz
Ububanzi bokujika kwe-pendulum:
Iphuzu lokulingana lisephuzwini B, ngakho-ke ukuphambuka okuphezulu kwe-pendulum kuyiphuzu C kanye nephuzu A elingama-5 cm ukusuka ephuzwini B.
Impendulo efanele ingu-B.

9. Inhlayiya enyakazayo isendaweni futhi ihamba ngendlela eboniswe esithombeni.
Uma ubukhulu kanye nemvamisa yokunyakaza kungu-4 cm no-2 Hz, khona-ke umzuzwana owodwa ngemva kwalokho inhlayiya itholakala ku-…
A. x = -2 cm bese iya ngakwesobunxele
B. x = -2 cm bese iya kwesokudla

Ingxoxo
Imvamisa engu-2 Hz isho ukuthi njalo ngomzuzwana, inhlayiya yenza ukudlidliza okubili. Uma indawo yokuqala ingu-2 cm, khona-ke ukudlidliza okukodwa kwenzeka lapho inhlayiya ithuthela ku--2 cm (amplitude 4 cm) bese ibuyela endaweni yayo yokuqala engu-2 cm.
Kukhona ukudlidliza okubili phakathi nomzuzwana owodwa ukuze ngemva komzuzwana owodwa inhlayiya ibe ku-x = 2 cm futhi iqhubekela kwesobunxele.
Impendulo efanele ngu-E.
10. Isikhathi esidingekayo ukuze i-pendulum idlidlize isuka ku-ABCBA yimizuzwana emi-2 ngebanga le-AC = 6 cm. Imvamisa kanye nobukhulu bokudlidliza kwe-pendulum...
