Physics is an ___-based science.

• A. Observation
• B. Experiment
• C. Theory
• D. Calculation

Answer: (A)

Observation drives physics. Scientists begin by watching and measuring how objects and systems behave—recording quantities like position, velocity, force, and energy to uncover consistent patterns. Those empirical findings provide the data that theories and laws must explain. In this view, experiments are built to test the predictions that arise from those observations, not to define the field without them. While calculation and theory are essential tools, the grounding of physics in real-world observations gives models their meaning and testability.
