What is the error in a ruler?
Physics Practical Skills Part 3: Systematic VS Random Errors
If a piece of equipment is not calibrated correctly (e.g. a wooden ruler has shrunk), all measurements will be offset by the same fraction. Systematic error.
For example, if I asked you to measure the length of a pen, you might get out your ruler, and declare the pen is 18.2 cm long. You wouldn't say that the pen is ...
