2 Ka'idar aiki-makamashi Ƙarfin da ba na kiyayewa ba Motsi a kan jirgin sama mai karkata tare da gogayya - Matsaloli da Magani

1. Toshe yana zamewa ƙasa da wani jirgin sama mai karkata tare da gogayya. Menene saurin toshewar lokacin da toshewar ta bugi ƙasa? Matsakaicin gogayya mai motsi shine 0.4. Saurin da aka samu sakamakon nauyi shine 10 m/s ².

An sani:

Tsawon farko (h)_o= 6m

Tsawon ƙarshe (h _t ) = 0 m

Saurin farko (v _o ) = 0 (toshewa da farko a lokacin hutawa)

Ma'aunin gogayya ta motsi (μ _k ) = 0.4

Aikin da aka yi a cikin hanyoyin thermodynamic - matsaloli da mafita

1. Ana matse iskar gas mai kyau daga jiha ta 1 zuwa jiha ta 2 kamar yadda aka nuna a jadawalin da ke ƙasa. Kayyade aikin da iskar gas ɗin ta yi.

Magani

Lita 1 = 0.001 ^m3

An sani:

Matsi 1 (P1 ₎ = 10 kPa = 10,000 Pa = 10,000 N/m ²

Matsi na 2 (P2 ₎ = 20 kPa = 20,000 Pa = 20,000 N/ ^m2

Motsin Momentum da Motsin Projectile - Matsaloli da Magani

1. Za a saka ƙwallon 0.2-kg a cikin ramin C, kamar yadda aka nuna a hoton da ke ƙasa. Mai bugun ya buga ƙwallon cikin daƙiƙa 0.01 kuma hanyar BC ta yi tafiya cikin daƙiƙa 1. A ƙayyade girman ƙarfin don a iya saka ƙwallon cikin ramin C. Saurin gudu saboda nauyi shine 10 m/s ².

An sani:

Kusurwoyi (θ) = 60 ^o

Nauyin ƙwallon (m) = 0.2 kg

Saurin gudu saboda nauyi (g) = 10 m/s ²

Tazarar lokaci (Δt) = daƙiƙa 0.01

Juyawa na jikin da ke da tauri - matsaloli da mafita

Lokacin ƙarfi

1. Ƙarfi uku suna aiki akan wani katako mai tsawon mita 6, kamar yadda aka nuna a cikin hoton da ke ƙasa. Menene ƙarfin juyi mai zagaye da ke juya katakon a kusa da wurin O a matsayin axis na juyawa?

An sani:

Axis na juyawa a wurin O.

Ƙarfi 1 (F ₁ ) = F

Nisa tsakanin layin aikin F ₁ tare da axis na juyawa (r ₁ ) = mita 3

Springs a cikin jerin da layi ɗaya - matsaloli da mafita

1. Abu mai nauyin gram 160 yana mannewa a ƙarshen wata maɓuɓɓuga kuma canjin tsawon maɓuɓɓuga shine 4 cm. Menene canjin tsawon maɓuɓɓuga uku da aka haɗa a jere da layi ɗaya , kamar yadda aka nuna a cikin hoton da ke ƙasa?

An sani:

Canjin tsawon bazara (Δx) = 4 cm = 0.04 m

Nauyi (m) = gram 160 = 0.16 kg

Saurin gudu saboda nauyi (g) = 10 m/s ²
