Matambudziko Akagadziriswa muFizikisi Yekutanga

Maitiro ezvikamu - matambudziko nemhinduro

1. Chinhu A chine huremu hwe6-kg uye chinhu B chine uremu ye4-kg yakabatana netambo uye yakadhonzwa nesimba reF = 60 N, sezvakaratidzwa mumufananidzo uri pazasi. kukweshana kwekinetic pakati pepasi nezvinhu zvese zviri zviviri i0.5 (tan θ = ¾). Kuwedzera nekuda kwegiravhiti iri 10 m/s²Simba rekumanikidzwa rakakura sei?

Zvinozivikanwa:

Huremu hwechinhu A (m)_A) = 6 kg Maitiro ezvikamu - matambudziko nemhinduro 1

Huremu hwechinhu B (m_B) = 4 kg

Simba (F) = 60 Newton

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 che kuwanda kubva pamvura A kusvika pamvura 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 iri g = 10 m/s². Kureba kwepoindi B (h) chii?

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/s²

Kureba kweA (h)_A) = mamita makumi matanhatu

Nzvimbo yesimba rinokwevera pasi - matambudziko nemhinduro

1. Sarudza marongero e nzvimbo yegiravhiti yechinhu 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 cm²

Nzvimbo yepakati iri pa x axis (x₁) = 1/2 (2) = 1 cm

Nzvimbo yepakati iri pamutsetse we 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

Kuwedzera nekuda kwegiravhiti (g) = 10 m/s²

Vector - matambudziko nemhinduro

Vector uye Scalar

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

A. Simba - kukurumidza

B. Pressure - simba

C. Displacement - 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 pepakati kana kukurumidza kwe radial (a_R) uye kumhanya kwakanangana (v) mu kufamba kwakafanana kwedenderedzwa.

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 kwacho chii? Kuwedzera nekuda kwegiravhiti (g) = 9.8 ms^-2.

Zvinozivikanwa:

Shanduko ye simba rinobvira (ΔPE) = 4900 Joule

Misa yechinhu (m) = 50 kg

Kukurumidza kunokonzerwa negiravhiti (g) = 9.8 m/s²
