Faahfaahinta casharka

Natiijada casharka

I can describe and apply the relationship between mass and gravitational force.

Muuji qoraalka
The mass of an object is measured in kilograms. A force of about 10 N is needed to lift 1 kg on Earth. On Earth, a 1 kg mass pushes down on a surface with a force of about 10 N. There are 1000 g in 1 kg. Gravitational force, W = m × g

  5. 5. Jaantusku wuxuu muujinayaa gacan qabtay bir yar oo bir ah. Birta ma dhaqaaqeyso. Keebaa jumlado ah oo sax ah?

    • Ma jiraan xoogag ku shaqeeya birta.
    • Jawaabta saxda ah:Ma jiro xoog natiijo ah oo ku shaqeeya birta.
    • Waxaa jira xoog taageero ah oo kor u kaca oo ku shaqeeya birta.
    • Waxaa jira xoog cufisjiidad ah oo ku shaqeeya birta.
    • Birta ma lahan cuf (mass).

  6. 6. Nin cirbixiyeen ah ayaa ku soconaya Dayaxa isagoo sita dubbe. Maxaa ku dhacaya dubbaha haddii uu sii daayo?

    • Dubbuhu wuxuu kor u dhexeeyi doonaa, isagoo sii kordhinaya xawaaraha.
    • Dubbuhu wuxuu ku dhexeeyi doonaa meesha uu lagu sii daayay.
    • Dubbuhu wuxuu ku dhici doonaa dhulka Dayaxa, isagoo joogto ah xawaarihiisa.
    • Jawaabta saxda ah:Dubbuhu wuxuu ku dhici doonaa dhulka Dayaxa, isagoo sii kordhinaya xawaaraha marka uu dhaco.

  1. 1. Astronaut-ka ayaa la qaadayaa ul calan (flag pole) dhulka oo uu ku tagayaa Dayaxa. Kee ayaa run ah?

    • Jawaabta saxda ah:Cufka (mass) ul calanku waa isku midi.
    • Cufka ul calanku wuu yaraadaa.
    • Cufka ul calanku wuu kordhaa.
    • Miisaanka (weight) ul calanku waa isku midi.
    • Miisaanka ul calanku wuu yaraadaa.
