Equations
Equations in Physics
Equations are an important part of physics:

They allow us to predict what will happen if we know a few bits of information

They are universal, so they work the same way anywhere in the Universe
Rearranging Equations / Changing the Subject
Rearranging equations is an essential skill to master:

Decide which term you want to make the subject of the equation

Whatever you do to the lefthand side of the equation you do to the righthand side too
Rearranging Equations: Example A
A straightforward example of rearranging an equation.
Rearranging Equations: Example B
A slightly more complex equation that is rearranged.
Mathematical Symbols
This is a quick recap of the mathematical symbols you may come across in GCSE Physics.
Greek Letters
We quickly run out of letters to represent all the quantities we use at GCSE. We use letters from the Greek alphabet and here I run through the new symbols you will be using.
