To make these predictions in physics we need to measure the values of variable. Our measurements always have limits on their accuracy and precision.

The physics of steam engines and statistics - the start of our modern understanding of the universe.

When charges move an electric current is created. 

In the last century and a half, our knowledge of the nature and structure of matter has advanced considerably. But we still have much more to learn!

Advanced waves - the mathematics of simple harmonic motion with more diffraction and interference, resolution and the doppler effect.

Taking the ideas and concepts met in the previous units on Electrical Currents (topic 5) and Fields (topic 10) we look in more detail at how changes in electrical and magnetic fields can generate a potential difference - the key physics behind much of modern civilisation.
