1. 1.

   What is the definition of a fluid?

   Hint

   Consider how fluids react compared to solids.

2. 2.

   List two kinematic properties of fluids.

   Hint

   Think about how we measure motion in fluids.

3. 3.

   What defines a fluid's behavior under shear stress?

   • It maintains its shape
   • It deforms continuously
   • It remains rigid

   Hint

   Consider how different materials behave when forces are applied.

4. 4.

   True or False: In fluid mechanics, matter is classified into solids and fluids.

   • True
   • False

   Hint

   Think about how physicists categorize materials.

5. 5.

   You have two fluids: water (low viscosity) and honey (high viscosity) flowing over the same surface. Describe how their behavior would differ under the same shear force.

   Hint

   Think about how each fluid feels and moves.

6. 6.

   Using the material derivative, explain how the velocity of an element in a fluid changes when the fluid has both convection and shear acting on it.

   Hint

   Consider the interaction between the fluid's motion and the changes occurring in its environment.
