Mukuwona: a Kodi mu physics ndi chiyani? Chidziwitso chomwe muyenera kudziwa pa bangtuanhoan.edu.vn

Physics ndi phunziro lokakamizidwa kwa ophunzira masiku ano. Kuti tiphunzire bwino fizikisi, tifunika kudziwa kalembedwe, kuchuluka kwake, ndi zizindikiro za physics. M’nkhaniyi tikufuna kukufotokozerani kuti chizindikiro mufizikiki ndi chiyani? pamodzi ndi chidziwitso china cha Fizikisi koma muyenera kumvetsera.

Kodi mu physics ndi chiyani? a Kodi chizindikiro mu kalasi 8, kalasi 10 physics

Mu physics, anthu ambiri amasokoneza zizindikiro a ndi A. Kawirikawiri anthu ambiri amasokoneza ziwerengero ziwirizi. Mu physics imodzi ndi kuchuluka kwa mathamangitsidwe m/s. ndipo A ndiye muyeso wa gawo la m2.

Kuthamanga ndi kuchuluka komwe kumadziwika ndi kusintha kwa velocity yanthawi yomweyo pakapita nthawi. Kuthamanga ndi kuchuluka kwa njira komwe kumadziwikanso kuti kuchuluka kwa vector. Chigawo cha mathamangitsidwe wamba ndi utali wogawidwa ndi nthawi ya squared i.e. m/s2 (mamita/sekondi masikweya).

Fomula yothamangitsira a:

M’menemo:

  • a ndi gawo mathamangitsidwe m/s2.
  • Δv ndikusintha kwa velocity pompopompo.
  • v ndiye mayendedwe othamanga pompopompo pa nthawi t.
  • v0 ndiye mayendedwe othamanga nthawi yomweyo t0.
  • Δt ndi nthawi yofunikira kuti mutenge kusintha.

Funso 1: Chinthu chikuyenda molunjika ku ox axis ndipo pompopompo velocity vector v kukhala yosasintha.

  1. Velocity ya chinthucho nthawi zonse imakhala (+).
  2. Zogwirizanitsa nthawi zonse zimagwirizana ndi mtunda.
  3. Velocity ya chinthucho nthawi zonse imakhala (+).
  4. Zogwirizanitsa ndi ma velocity a chinthucho nthawi zonse amakhala ndi mtengo (+).

Yankho: C. Velocity ya chinthucho nthawi zonse imakhala (+).

Funso 2: Galimoto ikuyenda ndi v = 63 km/h, mwadzidzidzi dalaivala akuwona dzenje kutsogolo kwake, 82m kutali ndi galimoto. Anagunda mabuleki ndipo galimoto inafika padzenje ndikuyima. Kuwerengera mathamangitsidwe ndi braking nthawi.

Yankho:

Tili ndi v0 = 63 / 3.6 = 17.5 m/s

Kugwiritsa ntchito formula v mphamvu 2 – v0 mphamvu 2 = 2.aS

⇒a = v mpaka 2−v0 mpaka 2 = 2aS = -1.8673 (m/s2)

Pomwe a = (v−v0)/t ⇒ t = (v-v0)/a = 9,371 (s)

Funso 3: Galimoto imathamanga kuchokera ku 54km / h mpaka 27m / s panthawiyo, galimotoyo imayendetsa mtunda wa 80m. Werengani mathamangitsidwe nthawi ndi mathamangitsidwe galimoto.

Yankho:

s = 80m, vo = 54km/h = 15m/s, v = 27m/s

v2 – vo2 = 2as a = 3.15m/s2

v = vo + pa t = 3.8s

Funso 4: Ma elekitironi akuyenda ndi mayendedwe othamanga pompopompo 5.105 m/s amafulumizitsa kupita ku velocity yanthawi yomweyo ya 5.4,105 m/s. Kuwerengera nthawi ndi mtunda woyenda ndi ma elekitironi mukuthamanga, chifukwa kukula kwa mathamangitsidwe ndi 8,104 m / s2.

Yankho:

vo = 5.105(m/s); a = 8,104m/s2; v = 5,4.105m/s

v – vo = pa t = 0.5 s

v2 – vo2 = 2as s = 26,104 m

Funso 5: Galimoto A ikuyenda mumsewu wowongoka ndi liwiro lanthawi yomweyo la 40 km/h. Galimoto B imathamangitsa galimoto A yokhala ndi liwiro la 60 km/h. Tsimikizirani ma velocity pompopompo agalimoto B molingana ndi galimoto A ndi galimoto A pokhudzana ndi galimoto B.

Yankho:

Sankhani njira yabwino kuti mukhale mayendedwe a magalimoto awiriwo

vAD: kuthamanga kwagalimoto nthawi yomweyo Chibale pansi.

vBD: Kuthamanga kwanthawi yomweyo kwagalimoto B kutengera pansi.

vAB: velocity ventor wagalimoto B yokhudzana ndi galimoto A.

Malinga ndi njira yowonjezerera mayendedwe anthawi yomweyo, mayendedwe othamanga agalimoto A wachibale ndi galimoto B ndi:

vAB = vAD + vDB kapena vAB = vAD – vBD

Popeza magalimoto awiriwa akuyenda mbali imodzi, vAB = 40 – 60 = -20 (km / h) → njira yosiyana ndi yabwino.

⇒ vBA = 20(km/h) ndi vBA munjira yomweyo.
