Scientific Method & Scope of Physics — A/L Physics

How do I practise Scientific Method & Scope of Physics?

1 question with a worked solution

1. In the scientific method applied to empirical physics, which statement correctly distinguishes a scientific hypothesis from an established physical law?
   1. A) A hypothesis mathematically unifies all four fundamental forces, whereas a physical law is purely qualitative without mathematical equations
   2. B) A physical law can never be refuted or modified by any future observational evidence, whereas a hypothesis cannot be tested experimentally
   3. C) A hypothesis is universally true under all cosmic conditions, whereas a physical law is only valid in microscopic quantum systems
   4. D) A hypothesis is a tentative proposed explanation awaiting experimental verification, whereas a physical law summarizes consistent, universally validated empirical relationships

   Correct answer: D) A hypothesis is a tentative proposed explanation awaiting experimental verification, whereas a physical law summarizes consistent, universally validated empirical relationships

   In physics, a hypothesis is a falsifiable, tentative proposition based on initial observations. When repeatedly validated across diverse conditions without exception, concise mathematical descriptions of regularities become established physical laws (e.g., Newton's laws, Ohm's law).

   Show worked solution

   Step 1: Define hypothesis: provisional falsifiable proposal. Step 2: Define physical law: generalized empirical relationship supported by extensive observational validation. Answer: A hypothesis is a tentative proposed explanation awaiting experimental verification, whereas a physical law summarizes consistent, universally validated empirical relationships.
