Kufamba kwePendulum kakawanda:
Kuwanda kwezvizununguko (frequency) zvinoreva huwandu hwezvizununguko zvinoitika musekondi imwe chete, nepo nguva (period) iri nguva inodiwa kuti zvizununguke kamwe chete.
Pendulum inoita kudedera kamwe chete painofamba kubva paA kuenda kuB kuenda kuC yozodzokera kuB yozoenda kuA (A – B – C – B – A).
Kubva paA kusvika paC = 1/2 vibration, apo nguva inodiwa kuti 1/2 vibration iite 0,2 seconds.
Nguva inodiwa kuti kupedziswe kuzununguka kamwe chete i2 x 0,2 seconds = 0,4 seconds. Saka nguva yekuzununguka kwependulum = T = 0,4 seconds.
Kuwanda kwePendulum = f = 1/T = 1/0,4 = 2,5 Hertz
Kukura kwe pendulum swing:
Nzvimbo yekuenzana iri panzvimbo B, saka kutsauka kukuru kwependulum ipoindi C uye poindi A iri 5 cm kubva panzvimbo B.

Kukurukurirana
Kuwanda kwe2 Hz zvinoreva kuti sekondi yega yega, chinhu ichi chinoita kuzununguka kaviri. Kana nzvimbo yekutanga iri 2 cm, ipapo kuzununguka kamwe chete kunoitika kana chinhu ichi chikafamba kuenda ku -2 cm (amplitude 4 cm) uye chobva chadzokera panzvimbo yacho yekutanga ye2 cm.
Kune kuzununguka kuviri mukati mesekondi imwe chete zvekuti mushure mesekondi imwe chete, chidimbu chidiki chinosvika pa x = 2 cm uye chiri kufamba kuruboshwe.

Kukurukurirana
Nguva (T) = masekondi 2
Kuwanda (f) = 1/T = 1/2 = 0,5 /sekondi = 0,5 Hertz
Kukura (A) = 1/2 (6 cm) = 3 cm
Mhinduro chaiyo ndiA.
