pressure

    Cards (9)

    • describe pressure in fluid
      perpendicular force exerted on surface
    • describe affect of increased density on pressure
      increase pressure due to more particles to collide
    • describe affect of increased depth on pressure
      increase pressure due to more particles above object causing weight increase
    • describe upthrust
      upward resultant force of submerged object as higher pressure below object than above
    • describe factors causing floating
      upthrust larger than weight
    • describe factors causing sinking
      weight larger than upthrust
    • describe atmospheric pressure
      air particles colliding with surface
    • describe affect of increasing altitude on atmospheric pressure
      decrease pressure due to less particles so collisions and weight above decrease
    • describe affect of increasing altitude on atmospheric pressure
      decrease pressure due to less particles so collisions and weight above decrease
