15.2 Pressure in fluids (physics only)

Card 1 of 27

What produces atmospheric pressure on a surface?

A

Their particles can move past one another, allowing flow.

B

Air-particle collisions exert force per unit area.

C
  • Pressure is greater on the lower surface.
  • The resultant fluid force is therefore upward.
D
  • There is less overlying air.
  • Less compression gives lower air density.
  • Fewer collisions give less force per unit area.
