Mafupipafupi a kugwedezeka kwa pendulum:
Mafupipafupi ndi chiwerengero cha kugwedezeka komwe kumachitika mu sekondi imodzi, pomwe nthawi ndi nthawi yomwe imafunika kuti munthu agwedeze kamodzi.
Pendulum imapanga kugwedezeka kamodzi ikasuntha kuchoka pa A kupita ku B kupita ku C kenako kubwerera ku B kenako kupita ku A (A – B – C – B – A).
A mpaka C = 1/2 kugwedezeka, pomwe nthawi yofunikira kuti munthu agwedeze 1/2 ndi masekondi 0,2.
Nthawi yofunikira kuti mumalize kugwedezeka kamodzi ndi masekondi awiri x 0,2 = masekondi 0,4. Choncho nthawi ya kugwedezeka kwa pendulum = T = masekondi 0,4.
Kuchuluka kwa pendulum = f = 1/T = 1/0,4 = 2,5 Hertz
Kukula kwa kugwedezeka kwa pendulum:
Malo olingana ali pa mfundo B, motero kusiyana kwakukulu kwa pendulum ndi mfundo C ndi mfundo A yomwe ili 5 cm kuchokera pa mfundo B.
Yankho lolondola ndi B.
6. 
Yang'anani chithunzicho!
Pendulum imasinthasintha mu chitsanzo P→Q→R→S→T, chiwerengero cha kugwedezeka ndi….
A. ½ kugwedezeka
B. ¾ kugwedezeka
Kugwedezeka kwa C. 1
D. 2 kugwedezeka
Zokambirana
Pendulum imasinthasintha mu kapangidwe kake P→Q→R→S→T→S→R→Q→P = kugwedezeka 1
Pendulum imasinthasintha mu kapangidwe kake P→Q→R→S→T = ½ kugwedezeka
Yankho lolondola ndi A.
7.
Yang'anani pendulum pachithunzi chotsatira!
Ngati pendulum isuntha kuchokera ku A→B→C→B→A→B, chiwerengero cha kugwedezeka komwe kumachitika ndi…
A. 5 kugwedezeka
B. Kugwedezeka kwa 2 ½
Kugwedezeka kwa C. 2
D. Kugwedezeka kwa 1 ¼
Zokambirana
Pendulum imasuntha kuchokera ku A→B = ¼ kugwedezeka
Pendulum imasuntha kuchokera ku A→B→C = 2/4 kugwedezeka = ½ kugwedezeka
Pendulum imasuntha kuchokera ku A→B→C→B = ¾ kugwedezeka
Pendulum imasuntha kuchokera ku A→B→C→B→A = 4/4 vibration = 1 vibration
Pendulum imasuntha kuchokera ku A→B→C→B→A→B = 1 ¼ kugwedezeka
Yankho lolondola ndi D.
8.
Yang'anani chithunzicho!

Zokambirana
Pendulum imasinthasintha ndi mawonekedwe a C→A = ¼ kugwedezeka
Pendulum imasinthasintha mu kapangidwe C→A→B = 2/4 kugwedezeka = ½ kugwedezeka
Pendulum imasinthasintha mu kapangidwe C→A→B→A = ¾ kugwedezeka
Pendulum imasinthasintha mu kapangidwe C→A→B→A→C = 4/4 kugwedezeka = 1 kugwedezeka
Pendulum imasinthasintha mu kapangidwe C→A→B→A→C→A = 1 ¼ kugwedezeka
Pendulum imasinthasintha mu kapangidwe C→A→B→A→C→A→B = 1 ½ kugwedezeka
Yankho lolondola ndi C.
9. Tinthu tomwe tikuyenda mozungulira timakhala pamalo omwe akuwonetsedwa pachithunzichi.
Ngati matalikidwe ndi mafupipafupi a oscillation ndi 4 cm ndi 2 Hz, ndiye kuti pambuyo pa sekondi imodzi tinthu timeneti timakhala pa…
A. x = -2 cm ndipo imapita kumanzere
B. x = -2 cm ndipo imapita kumanja
C. x = 0 cm ndipo imapita kumanja
D. x = 0 cm ndipo imapita kumanzere
E. x = 2 cm ndipo imapita kumanzere
Zokambirana
Kuchuluka kwa 2 Hz kumatanthauza kuti sekondi iliyonse, tinthu tating'onoting'ono timapanga kugwedezeka kawiri. Ngati malo oyamba ndi 2 cm, ndiye kuti kugwedezeka kamodzi kumachitika pamene tinthu tating'onoting'ono timapita ku -2 cm (amplitude 4 cm) kenako n'kubwerera pamalo ake oyamba a 2 cm.
Pali kugwedezeka kawiri pa sekondi imodzi kotero kuti pambuyo pa sekondi imodzi tinthu timeneti timakhala pa x = 2 cm ndipo tikupita kumanzere.
Yankho lolondola ndi E.
10. Nthawi yofunikira kuti pendulum igwedezeke kuchokera ku ABCBA ndi masekondi awiri ndi mtunda wa AC = 6 cm. Mafupipafupi ndi kutalika kwa kugwedezeka kwa pendulum ndi...
A. 0,5 Hz ndi 3 cm
B. 0,5 Hz ndi 6 cm
C. 1,0 Hz ndi 6 cm
D. 2,0 Hz ndi 12 cm
Zokambirana
Nthawi (T) = sekondi imodzi
Kuchuluka kwa nthawi (f) = 1/T = 1/2 = 0,5/sekondi = 0,5 Hertz
Kukula (A) = 1/2 (6 cm) = 3 cm
Yankho lolondola ndi A.
