Liwiro lapakati ndi liwiro lapakati - mavuto ndi mayankho

Mavuto Othetsedwa mu Linear Motion - Liwiro lapakati ndi liwiro lapakati

1. Galimoto imayenda mumsewu wowongoka kupita kum'mawa kwa mamita 100 mu masekondi 4, kenako imayenda kumadzulo kwa mamita 50 mu sekondi imodzi. Dziwani liwiro lapakati ndi liwiro lapakati.

Anakonza

Mtunda = mamita 100 + mamita 50 = mamita 150

Kusuntha = mamita 100 – mamita 50 = mamita 50, kum'mawa.

Nthawi yatha = masekondi 4 + sekondi imodzi = masekondi 5.

Liwiro lapakati = Mtunda / nthawi yapita = mamita 150 / masekondi 5 = mamita 30/sekondi.

Liwiro lapakati = Kusamuka / nthawi yatha = mamita 50 / masekondi 5 = mamita 10/sekondi.

Onaninso  Kuyenda pa ndege yopendekeka popanda mphamvu yokangana - kugwiritsa ntchito lamulo la Newton la mavuto oyenda ndi mayankho ake

2. Munthu amayenda mamita 4 kum'mawa mu sekondi imodzi, kenako amayenda mamita atatu kumpoto mu sekondi imodzi. Dziwani liwiro lapakati ndi liwiro lapakati.

Anakonza

Liwiro lapakati ndi liwiro lapakati - mavuto ndi mayankho 1Mtunda = mamita 4 + mamita 3 = mamita 7

Kusamutsidwa = = mamita, kumpoto chakum'mawa.

Nthawi yatha = sekondi imodzi + sekondi imodzi = masekondi awiri.

Liwiro lapakati = mtunda / nthawi yapita = mamita 7 / masekondi awiri = mamita 3.5/sekondi

Liwiro lapakati = kusuntha / nthawi yapita = mamita 5 / masekondi awiri = mamita 2.5/sekondi

3. Wothamanga amayenda mozungulira Njira yozungulira ya rectangle yokhala ndi kutalika = mamita 50 ndipo m'lifupi = mamita 20. Mukayenda mozungulira njira yozungulira kawiri, wothamanga amabwerera komwe amayambira. Ngati nthawi yapita = masekondi 100, dziwani liwiro lapakati ndi liwiro lapakati.

Anakonza

Mzere wozungulira wa rectangle = 2 (mamita 50) + 2 (mamita 20) = mamita 100 + mamita 40 = mamita 140.

Amayenda mozungulira bwalo lamakona awiri = 2 (mamita 140) = mamita 280.

Mtunda = mamita 280.

Kusamuka = ​​mamita 0. (wothamanga kubwerera ku poyambira)

Liwiro lapakati = mtunda / nthawi yapita = mamita 280 / masekondi 100 = mamita 2.8/sekondi.

Liwiro lapakati = kusamuka / nthawi yapita = 0 / masekondi 100 = 0.

  1. Mtunda ndi kusamuka
  2. Liwiro lapakati ndi liwiro lapakati
  3. Liwiro lokhazikika
  4. Kuthamanga kosalekeza
  5. Kuyenda kwaulere kwa kugwa
  6. Kuyenda pansi mu kugwa kwaulere
  7. Kuyenda mmwamba ndi pansi mu kugwa kwaulere
