Huremu nehuremu - matambudziko nemhinduro

Matambudziko akagadziriswa mumitemo yaNewton yekufamba - Mass, uye huremu

1. Huremu hwehuremu hwe1 kg pamusoro penyika ndi… g = 9.8 m/s ²

Zvinozivikanwa:

Huremu (m) = 1 kg

Kumhanya kunokonzerwa negiravhiti pamusoro peNyika (g) = 9.8 m/s ²

Zvinodiwa: huremu (w)

Solution:

w = mg

m = huremu (Chikamu cheSI chehuremu ikirogiramu, kg)

g = kukurumidza kunokonzerwa negiravhiti (Chikamu cheSI che g i m/s ² )

w = uremu (Chikamu cheSI che w i kg m/s ² kana Newton)

Weight:

w = (1 kg)(9.8 m/s ² ) = 9.8 kg m/s ² = 9.8 Newtons

(a) Dhirowa simba regiravhiti (huremu) rinoita basa pachinhu kana chinhu chacho chakamira patafura, sezvakaratidzwa mumufananidzo (a).

(b) Dhirowa simba regiravhiti (huremu) nezvinhu zviri mariri zvinoshanda pachinhu chiri kutsvedza pasi chakarerekera , sezvakaratidzwa pamufananidzo (b)

mhinduro

Kurerekera kwehuremu kuri pasi kwakananga pakati peNyika.

w _x = chikamu chakatarwa chehuremu uye w _y = chikamu chakamira chehuremu

3. Huremu hwebhokisi i1 kg uye kumhanyisa nekuda kwesimba rinokwevera pasi i9.8 m/s ^2. Tsvaga (a) huremu (b) chikamu chakatarwa uye chikamu chakamira chehuremu.

mhinduro

Huremu : w = mg = (1 kg)(9.8 m/s ² ) = 9.8 kg m/s ² = 9.8 Newtons

Chikamu chakatambanudzwa chehuremu:

w _x = w sin 30 ^o = (9,8 N)(0,5) = 4.9 Newtons

Chikamu chakamira chehuremu:

w _y = w cos 30 ^o = (9.8 N)(0.5√3) = 4.9√3 MaNewton
