Introduction to Physics: Work, Energy, and Power

Have you ever wondered how physical forces move objects and how we measure the effort behind that movement? Understanding the core relationships between work, energy, and power is the key to unlocking the laws of physics that govern our daily lives. This course guides you through these fundamental concepts step-by-step, helping you build a strong foundation in classical mechanics. By completing this course, you will transition from learning basic definitions to confidently analyzing physical systems. You will learn to calculate mechanical work, distinguish between different forms of energy, and understand how power determines the speed at which tasks are completed. What you'll learn: - Define and calculate mechanical work using force and displacement in Joules - Distinguish between kinetic and potential energy and explain their transformations - Measure and analyze power as the rate of doing work in Watts - Apply the law of conservation of energy to basic physical systems - Solve foundational physics equations through structured written practice The course begins with essential terminology, basic concepts, and unit definitions before moving into practical formulas and real-world scenarios. You will progress at your own pace through clear written explanations and step-by-step problem-solving examples. This course is designed for absolute beginners, students, or anyone looking to refresh their basic physics knowledge from the ground up. No prior science background is required.
