This section is the place to start if you are commencing your course or kicking your revision into gear. It's probably not the most inspiring section, but having a good understanding of the basics will pay off in the topics.

Most of this material is in the data booklet or taught independently in the Maths Studies and Mathematics courses, but it's always quicker to have memorized content for fluency. Every 20 seconds adds up!

### Mathematical requirements

In physics, maths is used as a tool to solve problems related to the relationships between quantities.

### Greek alphabet

The letters of the Greek alphabet (almost all will be used)

### Units

There are 6 fundamental units we will use (not the candle) and a whole load of derived ones.

### Prefixes

You actually get a list of these in the databook but it's better if you know them.

### Presenting data

There are a few rules to follow when presenting data...

### Error and uncertainty

An error is the difference between the value you determine and the true value. Given that we collect data in experiments, and that our measuring instruments are not perfectly sensitive, there will always be an uncertainty in our value. Â

### Vectors

Adding vectors in 1D and 2D plus taking components of a vector.
