- In physics, maths is used as a tool to solve problems related to the relationships between quantities.
- Without basic maths skills you could still understand some concepts but would not be able to solve problems.
- Sometimes the language of maths is used to explain and describe not just perform calculations.
- Qualitative descriptions of data include the direction and relationship in which two variables change (e.g. as time increases, distance increases proportionally).
- Quantitative descriptions of data include numerical values (e.g. the speed of the object is 5ms-1).
- Graphs are visual representations used to represent relationships.
In physics, data collected from experiments and answers to problems are rarely nice easy whole numbers. This page shows some of the considerations you should have when presenting a number. When writing down a value from an experiment, we should...
