1.1 Energy Stores, Transfers and Power

In this module, you will develop a clear understanding of energy and how it is used in physical systems. You will begin by learning what systems are and exploring the different types of energy, as well as important ideas such as total energy, net energy, and closed systems. You will then see how changes in systems happen through energy transfers, using familiar everyday examples.

You will also learn how to calculate different types of energy transfers, including the energy of moving objects, objects raised above the ground, and energy stored in springs. The module will then introduce specific heat capacity, helping you understand why different materials heat up and cool down at different rates and how to calculate energy changes when materials are heated or cooled.

Finally, you will explore power, learning how to compare how powerful different systems are and how to calculate power. Throughout the module, you will apply these ideas to real-life situations to build confidence and exam skills.
