Foundations of Physics: Force, Work, and Energy

Physics does not have to be intimidating. By understanding how forces shape our world and how energy transfers, you can unlock a fundamental appreciation of how things move and interact. This text-based course guides you through the core concepts of mechanics, breaking down mathematical formulas into clear, conceptual explanations. You will transition from basic definitions to confidently solving practical physics problems involving force, work, and power. What you'll learn: Understand foundational concepts of force, displacement, and mass; Calculate work done on objects using key algebraic formulas; Differentiate between kinetic, potential, and mechanical energy; Apply the law of conservation of energy to real-world scenarios; Analyze power and efficiency in mechanical systems; Practice solving physics word problems with structured, written examples. The journey begins with essential terminology and the basic laws of motion, establishing a solid conceptual baseline. From there, you will explore the mathematical relationships between force and displacement, culminating in practical exercises that reinforce your understanding of energy conservation. This course is designed for high school students, self-learners, and anyone seeking a clear introduction to physics. No prior physics experience is required, though a basic understanding of pre-algebra is helpful. Start reading today and build a strong foundation in physical science.
