Reading Guide
Who this book is for
For biology and other students taking a one-year introductory physics course with algebra and trigonometry. The author distinguishes this route from his calculus-based text for physical science and engineering. It provides a free way to build physical reasoning when a standard university-physics treatment assumes more mathematics than the reader currently has.
Prerequisites
Algebra, trigonometry, scientific notation and graph reading. Core material does not require calculus; sections that use it are optional and should be approached with the appropriate mathematics.
What it covers
The introductory sequence connects physical models with quantitative problem solving across the major first-year topics. Its algebra-based organization allows students to work on interpretation, units and approximations while gradually strengthening their mathematical tools. Optional calculus material offers an extension without defining the core entry requirement.
How to use it
Before calculating, draw the situation and choose a physical principle that could relate the known and unknown quantities. Estimate the likely size of the result, and keep units throughout the calculation. Explain the meaning of a graph before extracting a number from it. After solving, change a parameter or consider a limiting case to see whether the model still gives a sensible prediction.
