Faahfaahinta casharka

Natiijada casharka

I can clearly describe how to measure speed and explain how I can do this accurately.

Muuji qoraalka
The instantaneous speed of an object is the speed at a particular moment in time. For an accurate measurement a person needs to be in line with the observation. Manual timing can lead to a range of timing errors. Repeat readings can reduce the effect of random errors. Some readings are anomalous and these should not be used in caluations of averages.

Imtixaannada

  1. 1. Mid ka mid ah isla'egyadan ayaa muujinaya sida masaafada la socday loo xisaabin karo iyadoo la adeegsanayo xawaaraha celceliska (average speed) iyo waqtiga?

    • masaafada la socday = xawaaraha - waqtiga
    • masaafada la socday = xawaaraha + waqtiga
    • masaafada la socday = xawaaraha ÷ waqtiga
    • Jawaabta saxda ah:masaafada la socday = xawaaraha × waqtiga

  2. 2. Arday ayaa cabiray inta ay qaadanayso gaari (trolley) si uu u dhaco masaafo dhan 1.5 m saddex jeer oo kala duwan. Akhrintoodu waa 2.5 s, 2.1 s, iyo 2.0 s. Xisaabi celceliska wakhtiga dhaca.

    • 2.0 s
    • Jawaabta saxda ah:2.2 s
    • 2.5 s
    • 5.7 s
    • 6.6 s

  1. 1. Dooro akhrinta leh qalad weyn oo waqti ah oo ku jira xogtan waqtiga.

    • 4.25 s
    • 4.15 s
    • Jawaabta saxda ah:3.25 s
    • 4.20 s
    • 4.20 s

  2. 2. Mid ka mid ah kuwan ayaa kaa caawinaya inaad yarayso qaladaadka wakhtiga ee tijaabada gawaarida (trolley) ee dhulka ku wareegaya?

    • Fiirinta si toos ah dhinaca xariiqa dhamaadka.
    • Isticmaalka saacadda (stopwatch) oo leh saxnaan 0.001 s.

  3. 3. Sababtoo ah qalad wakhti ah, ardaygu wuxuu cabbiraa waqti ka dheer waqtiga saxda ah. Sidee tani u saameyn doontaa xawaaraha uu xisaabinayo ee gaari rogrogaya (rolling trolley)?

    • Ma jiri doonto saameyn.
    • Xawaaraha la xisaabiyay wuxuu ka dheereyn doonaa xawaaraha saxda ah.
    • Jawaabta saxda ah:Xawaaraha la xisaabiyay wuxuu ka gaabin doonaa xawaaraha saxda ah.
    • Xawaaraha la xisaabiyay wuxuu noqon doonaa mid aan qiyaas lahayn.
    • Ma awoodi doono inuu xisaabiyo xawaare.

  4. 4. Maxaa ka mid ah kuwan soo socda uu yahay habka ugu saxsan ee lagu qiyaaso waqtiga ay qaadanayso kubbad lagu tuuray dhinaca shaybaarka (lab-ka)?

    • isticmaalka saacad (timer) ku taal taleefanka gacanta
    • akhriska saacadda (clock) ee derbiga ku taal
    • isticmaalka saacad-joojin (stopwatch) ee dugsiga
    • Jawaabta saxda ah:samaynta fiidiyow (video) kubbadda oo taleefanka gacanta lagu duubo
