Faahfaahinta casharka

Natiijada casharka

I can describe and explain the relationship between the extension of a spring and the force stretching it.

Muuji qoraalka

A line of best fit can show the relationship between variables clearly. The extension of a spring increases the same amount for each equal sized increase in force. The extension of a spring is directly proportional to the force applied. A spring is elastic because it returns to its original length when a force is removed. Hooke's law describes the behaviour of springs.

Imtixaannada

1. Jaantusku wuxuu muujinayaa gariir (spring) ka hor iyo ka dib markii miisaan lagu daray. Waa maxay fiditaanka (extension) gariirka marka cufka (mass) la saaro?
- 0 cm
- 4.0 cm
- Jawaabta saxda ah:4.5 cm
- 10.5 cm
- 14.5 cm
2. Sawirku wuxuu muujinayaa arday ku qaadaya cabbirka fidinta (extension) ee spring-ga. Sidee ayuu ardaygu u wanaajin karaa saxnaanta cabbirka?
- Isticmaal spring gaaban si fidintu u gaabato.
- Isticmaal xisaab dheer si aad u gaadho spring-ga.
- Jawaabta saxda ah:Isticmaal set square si aad u hubiso in cabbirku yahay mid toosan (horizontal).
- Ka dhaqaaq xisaabta ka fog spring-ga si ay u dheellitirto.
- Isticmaal spring dheer si fidintu u gaabato.
3. Xoogga cufisjiidadka ee Dhulka waa 10 N/kg. Immisa cuf (mass) ayaa lahaan doona miisaan (weight) ah 1 N?
- 10 kg
- 1 kg
- 1000 g
- Jawaabta saxda ah:100 g
- 10 g
4. Waa maxay sababta ay muhiim u tahay in la qiyaaso fidinta (extension) ee spring-ga marka culeysyada (masses) laga qaadayo iyo sidoo kale marka la darayo?
- Tani waxay ka caawin doontaa in spring-ga la furo oo si fiican u fidiyo.
- Culeysyada ayaa laga yaabaa inay isbeddeen ka dib markii la daray.
- Jawaabta saxda ah:Si loo hubiyo saxnaanta (accuracy) qiyaasaha.
- Si loo isticmaalo culeysyo (masses) kala duwan oo badan.

1. Markee hadii la kala jiido goorma ayaa run ah?
- Dhererku wuxuu labanlaabmaa newton kasta oo xoog ah.
- Kordhintu waxay ku kordhaa si aan qiyaas lahayn.
- Kordhintu kuma xirna xoogga saameeya.
- Jawaabta saxda ah:Kordhintu waxay ku kordhaa qadar isku mid ah newton kasta oo xoog ah.
- Springs oo dhami waxay ku kala baxaan qadar isku mid ah newton kasta.
2. Maxaa ku dhacaya fiditaanka (extension) gariiradda haddii xoogga (force) ku shaqeeya uu kordho laga bilaabo 6 N ilaa 18 N?
- Waxay noqonaysaa saddex jeer ka yar.
- Waxay isku dhalaalaysaa (hal mar yar).
- Waxay isku mid tahay.
- Waxay labanlaabantaa.
- Jawaabta saxda ah:Waxay saddexlaabantaa.
3. Mid ka mid ah kuwan soo socda ayaa qeexaya khadka ugu habboon (line of best fit) ee garaafka ay labada doorsoome (variables) si toos ah isugu dhigmaan?
- Waa qalooc (curve).
- Jawaabta saxda ah:Waa xariiq toosan (straight line).
- Waa xariiqyo isku xira dhammaan dhibcaha xogta si sax ah.
- Wuxuu u dhow yahay meesha asalka ah (0,0).
- Wuxuu dhex maraa meesha asalka ah (0,0).
4. Ardayda qaarkood waxay ku darayaan xoog badan (force) isbiring (spring). Markasta oo ay ku daraan 1 N dheeri ah, kordhinta (extension) ayaa si weyn u kordheysa sidii la filayay. Maxaa ku dhacaya isbiringga marka xoogga laga qaado?
- Wuxuu dib ugu soo laaban doonaa dherer ka gaaban kan asalka ah.
- Wuxuu dib ugu soo laaban doonaa dhererkiisii asalka ahaa.
- Jawaabta saxda ah:Wuxuu dib ugu soo laaban doonaa dherer ka dheer kan asalka ah.
- Wuxuu dib uma soo laaban doono, wuxuuna ku sii joogi doonaa dhererka uu gaaray.
