2.1.2. Downward Force

Try these first

1. 1.

   What is the condition for equilibrium in fluid forces?

   Hint

   Think about balance.

2. 2.

   Define surface tension.

   Hint

   It's about fluid surfaces!

3. 3.

   What must the upward force equal in a fluid at rest?

   • Downward Force
   • Atmospheric Pressure
   • Net Force

   Hint

   Consider equilibrium conditions.

4. 4.

   True or False: Capillary action involves only downward forces.

   • True
   • False

   Hint

   Think of how fluids move in narrow spaces.

5. 5.

   Calculate the pressure exerted by water in a column of height 3 m; assume the density of water is 1000 kg/m^3.

   Hint

   Remember the formula involves density and height.

6. 6.

   A fluid system is connected with two different liquids. Discuss how you would approach analyzing the forces at equilibrium.

   Hint

   Consider using Pascal's law in your approach.
