Thinking Like a Physicist

This lesson introduces the habits that make physics useful: observing carefully, asking testable questions, building simple models, estimating before calculating, and checking results against reality. Rather than treating physics as a collection of formulas, learners will practice seeing it as a disciplined way to explain patterns in the physical world.

Because this is the first lesson in the measurement section, the focus stays on reasoning, evidence, assumptions, units, and scale. Detailed equations for motion, forces, waves, electricity, and modern physics will come later; here, the goal is to build the mental toolkit needed to approach those topics with confidence.
