Understand Physics Without Feeling Overwhelmed
Physics explains everything from a falling ball and a moving car to electricity, stars, black holes, and quantum technology.
Physics for Beginners by SB Luwang presents these ideas step by step using simple explanations, practical examples, equations, diagrams, experiments, and problem-solving methods.
The book begins with the foundations of measurement and motion before gradually moving into mechanics, energy, fluids, heat, waves, electricity, magnetism, atomic and nuclear physics, astronomy, relativity, and quantum physics.
What You Will Learn
