쉽게 배우는 대학기초물리 > 자연과학

이 책은 이공계열의 물리학 입문서로서 기본적인 내용을 간결하게 정리하고 알기 쉽게 설명하였다. 이 책의 목적은 이공계열 학과에서 전공 공부에 필요한 기본적인 물리량의 개념을 익히게 하는 데 있다. 충분한 양의 예제와 연습 문제를 수록하고, 특히 기초가 부족한 학생들도 스스로 공부할 수 있도록 문제 풀이 과정을 상세하게 기술하였다. 연습문제는 주요 핵심 개념을 파악할 수 있게 하는 문제들로 구성되어 있으며, 특히 공무원 임용시험에 출제된 문제를 많이 수록하여 각종 시험에도 도움이 되게 하였다.

대부분의 대학 교재들은 연습문제 풀이를 해 주지 않지만 이 책은 우선적으로 학생들이 쉽게 공부할 수 있도록 모든 연습문제의 정답과 풀이 과정을 기술하였다.
