Scientific Notation and Measurement Concepts

This video introduces the basics of physics, emphasizing its nature as a language expressed through mathematics. It covers the concept of measurement, units, and the International System of Units (SI). The video also explains scientific notation for handling large and small numbers and discusses multiples and submultiples of units.
