Work, Energy, and Power
Learning Time: 4-12 hours
Content: Work, energy, and power are concepts that examine energy conversion and mechanical work in physical systems. This topic covers the definition of work (Fd), potential and kinetic energy, power (W/t), and conservation of energy. TYT focuses on basic energy types and work, while AYT focuses on energy conversions and efficiency. The current 2025 curriculum also covers topics such as renewable energy and energy efficiency. Learning this topic forms the basis for the analysis of mechanical systems.
