GCSE Physics - Conservation of Energy #4

The video tutorial explains the conservation of energy principle, emphasizing that energy can be transferred, stored, or dissipated but not created or destroyed. It uses the example of a phone charging to illustrate energy transfer between electrical and chemical forms. The concept of open and closed systems is introduced, highlighting how energy and matter interact within these systems. The tutorial stresses the importance of understanding these concepts to apply them in various scenarios.

Explain how energy is transferred when charging a phone.

What forms can wasted energy take when using a device?

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