What we have learnt
- Physics explores the universe and its fundamental laws.
- The scientific method involves observation, questioning, hypothesizing, experimenting, analyzing, and concluding.
- Measurement and standardized units are crucial for scientific communication and data accuracy.
- Precision and accuracy are vital for reliable measurements, which are expressed using significant figures.
- Quantities in physics are classified as scalars or vectors, influencing how they are represented and analyzed.
Key Concepts
- -- Scientific Method
- A systematic, iterative process for scientific investigation, encompassing observation, hypothesis formation, experimentation, and conclusion.
- -- SI Units
- The International System of Units, a standardized system that provides a consistent framework for measuring physical quantities.
- -- Scalar and Vector Quantities
- Scalar quantities are described by magnitude alone, while vector quantities require both magnitude and direction for complete description.
- -- Precision vs Accuracy
- Accuracy refers to how close a measurement is to the true value, while precision refers to the consistency of multiple measurements.
- -- Significant Figures
- The digits in a measurement that convey its precision, including all known digits and one estimated digit.
