Correct answer: B. Energy
- A. Mass
- B. Energy
- C. Momentum
- D. All
Explanation
Bernoulli's equation is based on the conservation of energy along a streamline in a flowing fluid. It states that the total mechanical energy per unit mass of a fluid is constant along a streamline. This energy includes kinetic energy, potential energy, and internal energy per unit mass.

About Fluid Dynamics
Fluid flow is described through speed, pressure and density, including steady flow and the equation of continuity for conserving mass. Bernoulli's equation relates pressure, speed and height, while fluid drag and terminal velocity explain why a falling object eventually moves at constant speed when drag balances its weight.
