Ihe atụ 8 nke ajụjụ gbasara Iwu nke Abụọ nke Newton

1. Ihe nwere ibu nke kilogram 1 na-agagharị na ọsọ ọsọ nke mita 5/s²Kedụ ka ike sitere na ya nke na-akwali ihe ahụ si buru ibu?
Mkparịta ụka
A maara :
Ibu ihe (m) = 1 kg
Ọsọ ọsọ (a) = 5 m/s²
A jụrụ ike sitere na ya nke na-ebugharị ihe
Jawab :
Iwu nke Abụọ nke Newton kwuru na ọ bụrụ na e nwere ike sitere na ihe na-arụ ọrụ, ihe ahụ ga-enweta ọsọ ọsọ, ebe oke ọsọ ọsọ ahụ dabara kpọmkwem na oke ike sitere na ya ma na-agbanwe agbanwe na oke nke ihe ahụ. Ụzọ nke ọsọ ọsọ ihe ahụ bụ otu ihe ahụ na ntụziaka nke ike sitere na ya. N'ime mgbakọ na mwepụ:
Nkọwa usoro:
Sigma F = ike sitere na ya (nkeji mba ụwa bụ kg m/s² (a makwaara dịka Newton)
m = oke nke ihe ahụ (nkeji mba ụwa bụ kilogram, nke a kpọrọ 'kg')
a = osooso (nkeji mba ụwa bụ mita kwa sekọnd, nke a kpọchiri akpọchi m/s)²)
Ya mere, ike sitere na ya nke na-akwali ihe ahụ bụ:
2. Ibu nke blọk ahụ = 1 kg, F = 2 Newton. Oke na ntụziaka nke osooso blọk ahụ bụ…
Mkparịta ụka
A maara :
Ibu nke ngọngọ (m) = 1 kg
Ike (F) = Newtons 2
A jụrụ : nha na ntụziaka nke osooso nke blọk ahụ (a)
Jawab :
Ntuziaka nke osooso ngọngọ = ntụziaka nke ike F

3. Ibu nke blọk ahụ = 2 kg, F₁ = 5 Newton, F₂ = 3 Newton. Oke na ụzọ nke osooso nke blọk ahụ bụ…
Mkparịta ụka
A maara :
Ibu nke ngọngọ (m) = 2 kg
F₁ = 5 Newton
F₂ = 3 Newton
A jụrụ : nha na ntụziaka nke osooso nke blọk ahụ (a)
Jawab :
4. Ibu nke blọk ahụ = 2 kg, F₁ = 10 Newton, F₂ = 1 Newton. Oke na ụzọ nke osooso nke blọk ahụ bụ…
Mkparịta ụka
A maara :
Ibu nke ngọngọ (m) = 2 kg
F₂ = 1 Newton
F₁ = 10 Newton
F_1x = F.₁ Ogu 60^o = (10)(0,5) = 5 Newtons
A jụrụ : nha na ntụziaka nke osooso nke blọk ahụ (a)
Jawab :
Ntuziaka nke osooso ngọngọ = ntụziaka nke ike sitere na ya = ntụziaka nke F_1x

5. F₁ = 10 Newton, F₂ = 1 Newton, m₁ = 1 kg, m₂ = 2 kg. Oke na ụzọ nke osooso nke blọk ahụ bụ…

Mkparịta ụka
A maara :
Ibu nke blọk 1 (m₁) = 1 kg
Ibu nke blọk 2 (m₂) = 2 kg
F₁ = 10 Newton
F₂ = 1 Newton
A jụrụ : nha na ntụziaka nke osooso nke blọk ahụ (a)
Jawab :

Ntuziaka nke osooso ngọngọ = ntụziaka nke ike sitere na ya = ntụziaka nke F₁

6. Ọtụtụ ike na-arụ ọrụ n'ihe nwere oke ibu nke kilogram ise dịka egosiri na eserese a. Ọ bụrụ na ike esemokwu dị n'etiti ihe ahụ na bọọdụ ahụ efu, mgbe ahụ ọsọ ọsọ nke ihe ahụ na-enweta bụ...

A. 1 m/s²
B. 4 m/s²
C. 5 m/s²
D. 9 m/s²

Mkparịta ụka

A maara na:
Ụdị nke abụọ (F)₁) = 15 Newton (ntụziaka aka ekpe)
Ụdị nke abụọ (F)₂) = 10 Newton (ntụziaka aka ekpe)
Ụdị nke abụọ (F)₃) = 20 Newton (ntụgharị aka nri)
Ibu ihe (m) = kilogram 5
Ajụjụ: Ngwa ngwa nke ihe (a) nwetara
Azịza:

Ike sitere na ya:
∑F = F₁ +F₂ - F.₃
∑F = 15 + 10 – 20
∑F = 25 – 20
∑F = 5 Newton
∑F = 5 kg m/s²
Ntuzi nke ike sitere na ya bụ otu ihe ahụ dị ka ntụziaka nke ike 1 na ntụziaka nke ike 2, ya bụ, n'aka ekpe.
Usoro iwu nke abụọ nke Newton:
∑F = ma
5 kg m/s² = (5 kg) a
5 m / s² = (5) a
a = (5 m/s²) /5
a = 1 m/s²
Oke ọsọ nke ihe ahụ bụ 1 m/s². Nduzi nke osooso ihe = ntụziaka nke mmegharị ihe = ntụziaka nke ike sitere na ya = n'aka ekpe
Azịza ziri ezi bụ A.

7.

Lee onyonyo nke ike ndị na-arụ ọrụ na ihe a! Ọ bụrụ na ibu nke ihe ahụ bụ kilogram abụọ, ọsọ ọsọ nke ga-eme na ihe ahụ bụ...

A. 12,5 m/s²
B. 7,5 m/s²
C. 5,0 m/s²
D. 2,5 m/s²

Mkparịta ụka
A maara na:
Ụdị nke abụọ (F)₁) = 10 Newton (ntụziaka aka ekpe)
Ụdị nke abụọ (F)₂) = 10 Newton (ntụgharị aka nri)
Ụdị nke abụọ (F)₃) = 5 Newton (ntụgharị aka nri)
Ibu ihe (m) = kilogram 2
Ajụjụ: Ngwa ngwa nke ihe (a) nwetara
Azịza:
Ike sitere na ya:
∑F = F₂ +F₃ - F.₁
∑F = 10 + 5 – 10
∑F = 15 – 10
∑F = 5 Newton
∑F = 5 kg m/s²
Ntuzi nke ike sitere na ya dị ka ntụziaka nke ike 2 na ntụziaka nke ike 3 dị n'aka nri.
Usoro iwu nke abụọ nke Newton:
∑F = ma
5 kg m/s² = (2 kg) a
5 m / s² = (2) a
a = (5 m/s²) /2
a = 2,5 m/s²
Oke ọsọ nke ihe ahụ bụ 2 m/s²Ụzọ nke ọsọ nke ihe ahụ = ntụziaka nke mmegharị ihe ahụ = ntụziaka nke ike sitere na ya = n'aka nri
Azịza ziri ezi bụ D.

8. Ọtụtụ ike na-arụ ọrụ na ihe B dịka egosiri na foto a.
Ọ bụrụ na ibu nke ihe B = 4 kg, osooso nke B na-enweta bụ….
A. 2,5 m/s²
B. 4,0 m/s²
C. 5,0 m/s²
D. 9,0 m/s²
Mkparịta ụka
A maara na:
Ụdị nke abụọ (F)₁) = 20 Newton (ntụgharị aka nri)
Ụdị nke abụọ (F)₂) = 6 Newton (ntụgharị aka nri)
Ụdị nke abụọ (F)₃) = 10 Newton (ntụziaka aka ekpe)
Ibu ihe (m) = kilogram 4
Ajụjụ: Ngwa ngwa nke B (a) nwetara
Azịza:
Ike sitere na ya:
∑F = F₁ +F₂ - F.₃
∑F = 20 + 6 – 10
∑F = 26 – 10
∑F = 16 Newton
∑F = 16 kg m/s²
Ntuzi nke ike sitere na ya dị ka ntụziaka nke ike 1 na ntụziaka nke ike 1 dị n'aka nri.
Usoro iwu nke abụọ nke Newton:
∑F = ma
16 kg m/s² = (4 kg) a
16 m / s² = (4) a
a = (16 m/s²) /4
a = 4 m/s²
Oke ọsọ nke ihe ahụ bụ 4 m/s²Ụzọ nke ọsọ nke ihe ahụ = ntụziaka nke mmegharị ihe ahụ = ntụziaka nke ike sitere na ya = n'aka nri
Azịza ziri ezi bụ B.
