GCSE Physics - Energy Stores, Transferring Energy & Work Done #1

The video tutorial explains that energy is never created or destroyed but transferred between forms and objects. It covers various energy stores like thermal, kinetic, and potential energy, and how energy is transferred mechanically, electrically, by heating, or radiation. The concept of systems, both open and closed, is discussed, highlighting how energy is exchanged. Practical examples, such as a kettle and a train, illustrate these concepts. The video also differentiates between mechanical and electrical work done.

What is the principle that states energy is never created or destroyed?

Describe the different forms of energy mentioned in the text.

Explain the difference between an open system and a closed system.

How does energy transfer occur when a kettle is turned on?

What happens to the kinetic energy of a train when it applies the brakes?
