Aims of this episode:
- Identify the different forms of energy;
- Understand some examples of energy being transferred from one form to another;
- Explain what is meant by the “Conservation of Energy”.
Conservation of Energy
The golden rule when it comes to energy is that: “Energy cannot be created or destroyed, only transferred from one form to another.”
During the Big Bang, a lot of energy was created. Some of this energy was converted into matter (particles, atoms etc.) whilst some of it remained as energy. Ever since the Big Bang the amount of energy in the Universe has remained the same. During this time the energy has always taken different forms.
Forms of Energy
The main form of energy that you need to know for GCSE are:
- Gravitational Potential;
Energy can be stored in these forms (except for electrical and radiation). It can then be transferred from one store to another. The podcast episode will explain a number of different examples.
