Matsalolin da aka Magance a fannin Fizik na Asali

Haɗari - matsaloli da mafita

1. Abu A (3 kg) yana motsawa a gudun 8 m/s kuma abu B (5 kg) yana motsawa a gudun 4 m/s. Idan karo tsakanin abubuwan A da B yana da cikakkiyar roba, menene gudu na abubuwa A da B bayan karo?

An sani:

Mass na abu A (m)₁) = 3 kg

Nauyin abu B (m)₂) = 5 kg

The gudun na abu A (v)₁) = 8 ms^-1

Saurin abu B (v)₂) = 4 ms^-1

Vectors na raka'a - matsaloli da mafita

1. Abu yana motsawa a wani gudu na v = (2i − 1.5j) m/s. Menene sauyawa na abin bayan daƙiƙa 4?

An sani:

Bangaren kwance na saurin (v)_x) = 2 m/s

Bangaren tsaye na saurin (v)_y) = 1.5 m/s

Tazarar lokaci (t) = daƙiƙa 4

Matsar da Vector - matsaloli da mafita

1. Mutum yana tafiya daga wuri A zuwa wuri B, mita 600 a arewa; sannan zuwa wurin C, mita 400 a yamma; sannan zuwa wurin D, mita 200 a kudu; sannan ya ƙare a wuri E, mita 700 a gabas. Menene girman wurin sauyawa?

Magani:

An sani:

AF = AB – BF = AB – CD = 600 – 200 = 400 m

EF = DE - DF = DE - BC = 700 - 400 = 300 m

Ƙara vectors ta amfani da abubuwan haɗin kai - matsaloli da mafita

1. Vectors guda uku kamar yadda aka nuna a hoton da ke ƙasa.

V₁ = 30

V₂ = 30

V₃ = 40

Menene sakamakon vectors.

An sani:

V₁ = 30, kusurwa tsakanin V₁ kuma axis x = 30^o

Zane-zanen motsi na layi - matsaloli da mafita

1. Zana tazara (tsaye) da lokaci (a kwance) kamar yadda aka nuna a cikin hoton da ke ƙasa. Wani abu da aka huta da lamba…

Magani:

Lamba ta 3, wadda aka nuna ta hanyar layi madaidaiciya.

Matsakaicin gudu - matsaloli da mafita

1. Wani yana zagaye murabba'i mai tsawon mita 400 da faɗin mita 100, sau 12 a cikin awa 1. Menene waɗannan? matsakaicin gudu da matsakaita gudun?

An sani:

Tsawon murabba'i mai kusurwa huɗu = mita 400

Faɗin murabba'i mai kusurwa huɗu = mita 100

Da'irar murabba'i mai kusurwa huɗu = (mita 2 x 400) + (mita 2 x 100) = mita 800 + mita 200 = mita 1000

Nisa = mita 12 x 1000 = mita 12,000 = kilomita 12

An sani:

Mass na ruwa 2 (m₁= gram 200)

Zafin ruwa 1 (T)₁) = 30^oC

Nauyin ruwa 2 (m₂= gram 100)

1. Toshe A da taro na kilogiram 5, an sanya shi a kan jirgin sama mai santsi a kwance. Toshe B tare da nauyin kilogiram 3 da aka rataye a ƙarshen igiyar da aka haɗa da toshe A a kan pulley. Hanzarta saboda nauyi shine 10 m/s²Menene hanzari na tubalan biyu?

An sani:

Nauyin toshe A (m)_A) = 5 kg

Nauyin tubalan B (m)_B) = 3 kg

Saurin gudu saboda nauyi (g) = 10 m/s²

Motsin zagaye - matsaloli da mafita

1. Abu mai nauyin kilogiram 10 yana motsawa a cikin da'ira a gudun da ba ya canzawa 4 m/s. Idan radius na da'irar mita 0.5 ne, to:

1) Mitar da'ira ita ce 4/π Hz

2) A hanzarin tsakiya shine 32 ms^-2

3) A centripetal karfi shine 320 N

4) Lokacin shine 4π s.

Wadanne maganganu ne na gaskiya?
