Muenzaniso wekushandisa mitemo yaNewton panzvimbo yakatsetseka (isina kukweshana)

Mienzaniso miviri yekushandisa mitemo yaNewton kuti iite seyakatsetseka (isina kukweshana)

1. Huremu hwebhuroko i2 kg, kumhanyisa nekuda kwegiravhiti = 10 m/s²Sarudza (a) simba rinobuda rinokurumidzisa bhokisi (b) hukuru hwekukurumidzisa bhokisi.
Kukurukurirana
Zvinozivikanwa :
Huremu hwebhuroko (m) = 2 kg
Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s²
Kurema kwebhuroko (w) = mg = (2)(10) = 20 Newton
w_x = w chivi 30 = (20)(0,5) = 10 Newtons
w_y = w cos 30 = (20)(0,5√3) = 10√3 MaNewton
Mhinduro:
(A) simba rinobuda rinokurumidzisa bhokisi
Nzvimbo yakatsetseka yakatsetseka uko kunofungidzirwa kuti hakuna kukweshana. Saka simba rinokanganisa kufamba kwebhokisi rinongori w chete_x
(B) kukurumidza kukuru kwebhuroko
Kukura kwekumhanya kwebhuroko iri 5 m/s², divi rekumhanya kwebhuroko riri pasi.

2. Bhokisi iri rakatsetseka, risina kukweshana. Huremu hwebhokisi iri 3 kg, uye kukurumidza kunokonzerwa negiravhiti i10 m/s.². Tsvaga hukuru hwesimba F kana (a) bhokisi richiripo (b) bhokisi richidzika pasi nekumhanya kwe2 m/s² (c) bhokisi rinofamba richikwira kumusoro nekumhanya kunogara kuripo kwe2 m/s².
Kukurukurirana
Zvinozivikanwa :
Huremu hwebhuroko (m) = 3 kg
Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s²
Kurema kwebhuroko (w) = mg = (3)(10) = 30 Newton
w_x = w chivi 30 = (30)(0,5) = 15 Newtons
w_y = w cos 30 = (30)(0,5√3) = 15√3 MaNewton
Mhinduro:
(a) Sarudza F kana bhokisi riri panze.
Mutemo wekutanga waNewton unoti chinhu chinomira kana simba rinobuda riri zero.
(b) Sarudza F kana bhokisi richidzika pasi nekumhanya kwe2 m/s²
(c) Sarudza F kana bhokisi richikwira kumusoro nekumhanya kunogara kuripo kwe2 m/s²
