Physical World deals with the basic study of science, mathematics, natural sciences, forces, physics, and their impact and uses. It provides students with a fundamental understanding of the past and the development of laws in physics. This chapter introduces the importance of physics, explaining how it helps us understand the world around us—how things move, why objects fall, and much more.

Units and Dimensions: Explore the concept of units, dimensions, and their importance in scientific measurements. Discuss fundamental units (like meter, kilogram, second) and derived units (such as velocity, acceleration, force).

Significant Figures: Explain how to determine the precision of measurements using significant figures. Discuss rules for rounding off numbers and maintaining accuracy.

Error Analysis: Dive into error types (systematic and random) and methods to minimize errors in measurements. Cover topics like absolute error, relative error, and percentage error.

Scientific Notation: Introduce scientific notation as a concise way to express large or small numbers. Discuss how it simplifies calculations and comparisons.

Measuring Instruments: Describe common measuring instruments (rulers, vernier calipers, micrometers, etc.) and their usage. Highlight their precision and limitations.
