Arximed kuchini o`rganish.
Ishning maqsadi: Arximed kuchini qanday kattalilarga bog`liqligini tajriba yordamida o`rganish.
Kerakli jihozlar: Dinamometr, tarozi, teng massali turli hajimdagi yuklar, menzurka, arximed chelagi va tuzli suv.
Ishning bajarish tartibi:

• 
  Arximed kuchini dinamometr yordamida aniqlash:
  
• 
  Jism og`irligini havoda dinamometr yordamida o`lchaymiz va 1-jadvalga yozamiz.
  
• 
  Aynan shu jismni og`irligini suvga to`liq botgan holat uchun o`lchaymiz va 1-jadvalga yozamiz.
  
• 
  Formuladan Arximed kuchini topamiz hamda qiymatni 1-jadvalning mos ustuniga yozamiz.
  
• 
  Yuqoridagi o`lchashlarni yana ikki marta takrorlaymiz va formuladan o`rtacha qiymatni topamiz.
  
• 
  Ushbu qiymatni jism suvga to`liq botganda toshib chiqan suvning og`irligi bilan taqoslaymiz.

• 
  Arximed kuchini qiymati qanday kattaliklarga bog`liqligini o`rganish.
  
• 
  Massalaridan bo`lgan alyuminiy, temir va mis silindrlarni og`irligini suvga to`liq botgan holari uchun aniqlaymiz va ularga ta’sir qiluvchi Arximed kuchini formula orqali hisoblab topamiz.
  
• 
  Yuqorida o`tkazilgan tajribani tuzli suv bilan takrorlaymiz va natijalarni taqqoslab xulosani yozamiz:
