Learn about physics practical experiments in this collect of revision videos. Find out more about Hooke's law, Ohm's law, motion and density.

At its core, DFT postulates that the ground-state energy of a quantum system is a functional of the electron density. This principle, known as the Hohenberg-Kohn theorem, simplifies the problem of ...

You will complete eight required practical activities if you are studying GCSE Physics and twenty-one if ... Then use the equation \( \text{density} = \frac{mass}{volume}\). A student investigates ...
