Energy is one of the most important concepts in physics because it explains how and why things happen. Whether a car is accelerating, a roller coaster is moving, a battery is powering a device, or a power station is generating electricity, energy is being transferred and transformed. By understanding work, energy, and power, students gain a powerful framework for analyzing motion, machines, technology, and the physical world.
This course begins by exploring the fundamental relationship between work and energy. Students will investigate energy stores, learn how work transfers energy between systems, and examine the pathways through which energy moves and changes form. They will develop an understanding of conservation of energy and learn how energy flow diagrams can be used to represent energy transformations in real-world systems.
Students will then study mechanical energy, focusing on kinetic energy, gravitational potential energy, and elastic potential energy. They will learn how energy can be stored and transformed within moving systems and apply conservation principles to analyze situations involving motion, springs, and changing heights. Through calculations and problem-solving, students will develop quantitative skills used throughout physics and engineering.
The course continues with an investigation of power and efficiency. Students will examine how quickly energy is transferred or work is done, compare mechanical and electrical power systems, and explore why no machine is perfectly efficient. They will learn how efficiency is measured and how engineers seek to maximize useful energy output while minimizing energy losses.
Next, students will explore energy within systems and machines. They will investigate mechanical advantage, friction, energy losses, stability, and equilibrium while examining how energy flows through complex systems. By studying transportation, engineering structures, and technological devices, students will discover how energy principles are applied in practical design and problem-solving.
Throughout the course, students will investigate energy resources and sustainability. They will examine renewable energy technologies, batteries, fuel cells, energy storage systems, and emerging solutions to global energy challenges. By connecting physics concepts to environmental and technological issues, students will gain an appreciation for the role of energy in shaping society and the future of our planet.
