Misalai 3 na tambayoyin nauyi
1. Abu yana da nauyin kilogiram 1. Idan saurin gudu saboda nauyi = 10 m/s2, Nawa ne nauyin abin?
Tattaunawa
An sani :
Nauyin abu (m) = 1 kg
Saurin gudu saboda nauyi (g) = 10 m/s2
An tambaya Nauyin abu (w)
Jawab :
Tsarin nauyi:
w = mg
Bayani:
m = nauyi (naúrar ƙasa da ƙasa kilogiram ne, a takaice kg)
g = hanzari saboda nauyi (raka'o'in ƙasa da ƙasa mita ne a kowace daƙiƙa murabba'i, an taƙaita su m/s2)
w = nauyi (raka'o'in ƙasa da ƙasa sune kg m/s2 (aka Newton)
Nauyin abin shine:
w = (1 kg)(10 m/s2) = 10 kg m/s2 = 10 Newton
2. Duba hotuna (a) da (b) a ƙasa.
(a) Zana vector na nauyi na abu, a cikin hoto (a).
(b) Zana vector na nauyi, bangaren vector na nauyi a layi ɗaya da jirgin da aka karkata da kuma bangaren vector na nauyi a tsaye zuwa ga jirgin da aka karkata, a cikin hoton (b)!
Tattaunawa
Alkiblar nauyi (w) tana tsaye ne a ƙasa ko kuma a tsaye a tsakiyar duniya.
wx = ɓangaren kwance na nauyi da wy = ɓangaren tsaye na nauyi.
3. Idan nauyin abu = 1 kg da kuma hanzarin da aka samu sakamakon nauyi = 10 m/s 2 , a tantance (a) girman ƙarfin nauyi (b) girman ɓangaren vector ɗin ƙarfin nauyi wanda yake daidai da matakin da aka karkata da kuma girman ɓangaren vector ɗin ƙarfin nauyi wanda yake daidai da matakin da aka karkata.
Tattaunawa
Girman ƙarfin nauyi:
w = mg = (1 kg)(10 m/s2) = 10 kg m/s2 = 10 Newton
Girman ɓangaren ƙarfin nauyi a layi ɗaya da saman da aka karkata:
wx = w zunubi 30o = (10 N)(0,5) = 5 Newtons
Girman ɓangaren ƙarfin nauyi da ke tsaye a kan matakin da aka karkata:
Wy = w cos 30o = (10 N)(0,5√3) = 5√3 Newtons
