In simple language, these informative books offer explanations of the important concepts high school students encounter in science and physics classes. The series uses easy-to-understand examples throughout, to help students investigate and interpret scientific methodology, theories, and laws. Each title in the series covers a specific concept in physics, including the laws of motion and thermodynamics; kinetic and potential energy; gravity and magnetism; the characteristics of sound; and more. Colorful diagrams and photographs help to make this the perfect series for challenged high school students who might have trouble understanding required high school physics concepts. Physics is mandated as part of the high school curriculum, though some students find basic textbooks difficult to understand. Using diagrams and photographs to illustrate challenging concepts, this absorbing book is written in simple, easy-to-understand language specifically for those students. It includes well-organized descriptions of the concepts of gravitational force, electromagnetic, force and strong and weak forces, as well as examples of how these forces work in nature.
