⭕ A. The Newton's law of viscosity
⭕ B. The Newton's second law of motion
⭕ C. The Bernoulli's equation
⭕ D. The mountainous equation
📚 Explanation:
When fluid masses are subjected to uniform acceleration, their motion and forces are analyzed using Newton’s Second Law of Motion (F = ma).
🔹 This law states that the net force acting on a mass is equal to the product of its mass and acceleration.
🔹 It forms the foundation of fluid dynamics equations such as Euler’s and Navier-Stokes equations.
When fluid masses are subjected to uniform acceleration, their motion and forces are analyzed using Newton’s Second Law of Motion (F = ma).
🔹 This law states that the net force acting on a mass is equal to the product of its mass and acceleration.
🔹 It forms the foundation of fluid dynamics equations such as Euler’s and Navier-Stokes equations.
👉 Therefore, the correct answer is: B. The Newton's second law of motion
Key Concepts on Fluid Motion:
- Newton’s second law is the basis for analyzing fluid acceleration.
- Uniform acceleration implies constant force on a fluid mass.
- Used in deriving Euler’s equation of motion.
- Applies to both ideal and real fluids.
