Propagation of errors
When we add or subtract two values, we need to add their absolute errors.
When we multiply or divide two values, we need to add their relative errors.
Research Questions
- What is a systematic error?

- What is meant by the term ‘precision’?
- What is meant by the term ‘accuracy’?
- What is the uncertainty/error of a derived quantity given the absolute or relative uncertainties of the other physical quantity of which it is comprised?
- When we add or subtract multiple measurements, do we add their absolute uncertainties or their relative uncertainties?
- When we multiply or divide multiple measurements, do we add their absolute uncertainties or their relative uncertainties?
