What is the most accurate description of how science advances understanding of the natural world?
- Through a rigid adherence to traditional beliefs and established doctrines.
- Through intuitive leaps and subjective interpretations of events.
- Through a systematic process involving observation and experimentation. (correct)
- Through relying solely on theoretical frameworks developed by leading researchers.

Why is 'experimentation' considered a crucial component of the scientific process?
Why is 'experimentation' considered a crucial component of the scientific process?
- It limits the scope of scientific inquiry to only those phenomena that can be directly manipulated.
- It provides a means to validate or invalidate hypotheses through empirical testing. (correct)
- It ensures that all scientific theories are based on historical precedents.
- It allows scientists to disregard observational data in favor of controlled data.

What is Science?
Derived from the Latin word "scientia" meaning knowledge, it's a systematic process by which knowledge is acquired about the natural world. Uses observations and experimentation to describe, explain, and predict phenomena.

Study Notes
- Bernoulli's principle explains that a fluid's speed increases with a simultaneous decrease in pressure or potential energy.
Bernoulli's Equation
- $P_1 + \frac{1}{2} \rho v_1^2 + \rho g h_1 = P_2 + \frac{1}{2} \rho v_2^2 + \rho g h_2$
- P = absolute pressure of the fluid
- v = fluid velocity
- h = height of the pipe
- If pipe height remains constant and fluid velocity increases, pressure decreases.
Applications of Bernoulli's Principle
- Wings are designed to force air to travel faster over the top than underneath.
- Faster air has lower pressure, resulting in less pressure on top of the wing compared to the bottom.
- This pressure difference generates lift, enabling the airplane to fly.
Curveball
- A curveball's rotation causes it to drag air around, resulting in different relative air speeds on each side.
- Speed difference leads to a pressure difference causing deflection towards the lower pressure.
Atomizer
- Atomizers use a vertical tube in liquid and a horizontal tube connected at the top..
- Air blown over the vertical tube decreases pressure, causing liquid to rise and be atomized by the air stream.

Description
Bernoulli's principle relates fluid speed to pressure. Applications include airplane wings, where faster air above creates lift. Curveballs and atomizers also demonstrate this principle.
