1.10. Applying Newton's second law to fluid motion

Try these first

1. 1.

   What happens to pressure as you dive deeper into the ocean?

   Hint

   Think about the weight of water.

2. 2.

   State Pascal's Law in your own words.

   Hint

   Focus on the word 'equal'.

3. 3.

   What occurs to the pressure in a fluid as depth increases?

   • It decreases
   • It stays the same
   • It increases

   Hint

   Think about layers of water pressing down.

4. 4.

   Is Pascal's Law applicable only to liquids?

   • True
   • False

   Hint

   Think about pressure in the air.

5. 5.

   A diver descends to a depth of 30 meters. Calculate the pressure exerted on them, assuming water density is 1000 kg/m^3 and atmospheric pressure is 101325 Pa.

   Hint

   Don't forget to add atmospheric pressure.

6. 6.

   Discuss how design changes for a dam would differ at varying water heights and the implications for structural stability.

   Hint

   Consider how pressure affects the structure at various depths.
