Quick questions on Errors and uncertainties explained: H2 Physics Measurement

3short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.

What is q1?

Show answer

Distinguish between a random error and a systematic error, giving one example of each. [2 marks]

What is q2?

Show answer

A length is measured as

0.4382\ \text{m}

with an uncertainty of

\pm 0.005\ \text{m}

. Rewrite the result to an appropriate number of significant figures. [2 marks]
