Correct answer: B. Experiment and measurement
- A. Definition
- B. Experiment and measurement
- C. Hypothesis
- D. A collection of skills
Explanation
Physics is primarily based on experiment and measurement. It relies on conducting experiments to observe natural phenomena, collecting empirical data through measurements, and using this information to formulate theories and laws that describe and predict the behavior of the physical world. While hypotheses and theoretical frameworks are crucial in physics, the discipline's foundation lies in experimentation and precise measurement to validate or refute these hypotheses.

About Measurements
Physical quantities are expressed with SI base and derived units, while measurement limits are described through accuracy, precision, absolute and percentage error, and significant figures. Dimensional analysis checks equations, derives relationships and detects inconsistent units, but it cannot determine numerical constants or distinguish quantities with identical dimensions.
