Whether kinetic or potential, mechanical energy exists almost everywhere we look. Mechanical energy is defined through accessible text, explaining the basic concepts of matter, mass, motion, and forces such as gravity. Students will also read about the different ways that speed can be measured and learn how simple machines work. Sidebars profile scientists who formed our understanding of energy and photographs help clearly demonstrate principles of mechanical energy.
