Kuwanda kwevanhu uye kuenzana kwezvinhu - matambudziko nemhinduro

1. Chivharo chakaiswa muzvinwiwa zviviri zvine mhando dzakasiyana. Muzvinwiwa A, 0.6 chikamu chechinhu chiri mumvura. Muzvinwiwa B, 0.5 chikamu chechinhu chiri mumvura. Sarudza chiyero chehuwandu hwemvura A kune mvura B.

Zvinozivikanwa:

Kuwanda kwebhuroko = x Kuwanda kwevanhu uye kuenzana kwezvinhu - matambudziko nemhinduro 1

Chikamu chechinhu chiri mumvura A = 0.6

Kuwanda kwemvura A = y

Chikamu chechinhu chiri mumvura B = 0.5

Kuchengetedza simba remakanika panzvimbo dzakakombama - matambudziko nemhinduro

1. Kana kumhanya kwebhora panzvimbo A kuri 6 m/s, kumhanya kwebhora panzvimbo B kuri √92 m/s, uye kukurumidza nekuda kwegiravhiti kuri g = 10 m/s ^2. Ndeipi kukwirira kwepoindi B (h)?

Zvinozivikanwa:

Kumhanya kwebhora panzvimbo A (v)_A) = 6 m/s Kuchengetedza simba remakanika panzvimbo dzakakombama - matambudziko nemhinduro 1

Kumhanya kwebhora panzvimbo B (v _B ) = √92 m/s

Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s ²

Kureba kweA (h _A ) = 5.6 metres

Nzvimbo yesimba rinokwevera pasi - matambudziko nemhinduro

1. Sarudza makoronike epakati pesimba rinokwevera zvinhu pasi pechinhu sezvakaratidzwa mumufananidzo uri pazasi.

Solution: Nzvimbo yesimba rinokwevera pasi - matambudziko nemhinduro 1

Govanisa chinhu chacho kuita zvikamu zvitatu.

Nzvimbo yechikamu 1 (A ₁ ) = (2)(6) = 12 cm ²

Nzvimbo yepakati iri pa x axis (x ₁ ) = 1/2 (2) = 1 cm

Nzvimbo yepakati iri padivi re y (y ₁ ) = 1/2 (6) = 3 cm

Dzidziso yaTorricelli - matambudziko nemhinduro

1. Chubhu ine urefu hwemasendimita zana yakazadzwa nemvura. Buri Q riri pa10 cm kubva pasi. Ndeipi daro rakatarwa (x)?

Zvinozivikanwa: Dzidziso yaTorricelli - matambudziko nemhinduro 1

Kureba pakati pegomba nepamusoro pemvura (h) = 100 cm - 10 cm = 90 cm = 0.9 m

Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s ²

Vector - matambudziko nemhinduro

Vector uye Scalar

1. Pakati pesarudzo dzinotevera, idzo dziri scalar-vector pairs…

A. Simba - kukurumidza

B. Kumanikidzwa - simba

C. Kutamiswa - kumhanya

D. Mhepo yemagetsi - kumanikidzwa

Maikorosikopu yakabatana - matambudziko nemhinduro

Maikorosikopu yakabatana - matambudziko nemhinduro 1

Zvichibva pamufananidzo uri pamusoro, kukura kwese kwese chii? Ngatitii ziso rakajairika saka poindi iri pedyo (N) = 25 cm.

Zvinozivikanwa:

Huwandu hwezvinhu zvemuviri Zviyero zveZviyero - Matambudziko neMhinduro

Huwandu hwemuviri, mayuniti, zviyero - matambudziko nemhinduro 1

Zvichibva patafura iri pamusoro, huwandu hupi hune mayuniti chaiwo uye saizi.

Kukurumidza kweradiation - matambudziko nemhinduro

1. Ndeipi girafu iri pazasi inoratidza hukama huripo pakati pekumhanya kwepakati penzira kana kukurumidza kwe radial (a _R ) uye kumhanya kwemutsara (v) mukufamba kwakatenderera kwakafanana.

Kukurumidza kwe radial - matambudziko nemhinduro 1

Solution:

Simba rinogona kuwanikwa - matambudziko nemhinduro

Simba resimba rinokwevera pasi

1. Simba 4900 Joules rinoshandiswa kusimudza chinhu chine huremu hwe50 kg kusvika pakukwirira kweh. H kukwirira kweh chii? Kukurumidza kunokonzerwa negiravhiti (g) = 9.8 ms ^-2.

Zvinozivikanwa:

Kuchinja kwesimba rinogona kuwanikwa (ΔPE) = 4900 Joules

Huremu hwechinhu (m) = 50 kg

Kukurumidza kunokonzerwa negiravhiti (g) = 9.8 m/s ²

Nguva yekusagadzikana kwezvikamu - matambudziko nemhinduro

1. Mabhora maviri akabatana netsvimbo, sezvakaratidzwa mumufananidzo uri pazasi. Usafuratira huremu hwetsvimbo . Huremu hwebhora P i600 gramu uye huremu hwebhora Q i400 gramu. Ndeipi nguva yekusashanda kwehurongwa pamusoro peAB?

Zvinozivikanwa:

Chikamu chekutenderera chinonzi AB. Nguva yekusagadzikana kwezvikamu - matambudziko nemhinduro 1

m _p = magiramu 600 = 0.6 kg, m _q = magiramu 400 = 0.4 kg

r _p = 20 cm = 0.2 m, r _q = 50 cm = 0.5 m

Zvinodiwa: Nguva yekusashanda zvakanaka kwehurongwa
