The conservation of energy

"The Conservation of Energy" by Balfour Stewart is a book that explains the science of energy in simple terms. It's part of a series aiming to make scientific ideas easy to understand for everyone, whether they're scientists or just curious people. The book talks about what energy is, how it changes, and the rules it follows in different areas like physics, biology, and even psychology. Stewart begins by explaining the idea of energy, pointing out that while we may not know about individual particles, but there are laws that control groups of them. He uses examples from daily life to explain tricky scientific ideas, like how force and motion work together, how gravity affects things, and how energy plays a part in different changes. The beginning of the book suggests that it will systematically examine kinetic and potential energy and will build on basic ideas to help readers understand energy conservation throughout the universe.
