Scientific Method & Scope of Physics — A/L Physics

What must I remember about Scientific Method & Scope of Physics?

• Scientific Method: Systematic process of observation, hypothesis formation, experimental testing, data analysis, and theory/law formulation.
• Scope of Physics: Fundamental science governing matter, energy, space, and time across macrocosm (astronomy/cosmology) and microcosm (atomic/subatomic).
• Physical Models: Idealized abstractions (e.g., point mass, frictionless surface, ideal gas) designed to isolate key physical relationships without unmanageable mathematical complexity.
• Limitations of Scientific Laws: Laws of physics describe observed regularities within validated boundary conditions and domains of validity (e.g., Newtonian mechanics vs Relativistic/Quantum regimes).

1. Hypothesis vs Theory vs Law

   A Hypothesis is a tentative testable proposition; a Theory is a well-substantiated overarching explanation; a Law is a concise mathematical description of universal behavioral regularity.

2. Repeatability vs Reproducibility

   Repeatability refers to consistent results by the same observer with identical apparatus; Reproducibility refers to agreement across different observers, laboratories, and methods.

3. Principle of Falsifiability (Popper)

   Any scientific proposition must make empirically testable predictions capable of being proven false.
