Foundational Physics: Pressure, Work, Power, and Energy

Physics explains how forces act, work is performed, and energy is transferred in the physical world. Mastering the core principles of pressure, work, power, and mechanical energy provides an essential base for all science and technical fields. This text-based course breaks down introductory physics into structured, accessible written lessons. What you'll learn: Understand fundamental physical quantities, SI units, and core terminology. Calculate force, area, and pressure across solids, liquids, and gases. Apply formulas to evaluate mechanical work, power output, kinetic energy, and potential energy. Analyze the law of conservation of energy in simple mechanical systems. Explore real-world applications of energy transfer and efficiency in modern technology. The content starts with clear definitions and foundational laws before walking through written calculations and practical exercises. This course is designed for absolute beginners and middle school science students with no previous physics background required. Start reading today to build a strong baseline in mechanics and physical science.
