1.1 Length and time
Measuring Length
Measuring instrument Range Smallest scale division Common errors
measuring tape few meters 0.1cm - parallax error
- inaccurate setting at zero mark
meter rule 1 meter 0.1cm
vernier caliper 10cm 0.01cm - zero error
micrometer screw gauge 2cm 0.001cm
Measuring Time Intervals
Timing Device Example of use Common errors
clock/watch car parking parallax error of pointer
stopwatch time oscillations of pendulum reaction time error
electronic light-gate timer 100m race misalignment of light beams
- Timing devices need to be checked periodically to ensure they do not run too slow/fast
Measuring Mass and Volume
Regular solid Irregular solid Liquid
mass electronic balance = total mass − beaker mass
displacement/eureka can
(volume displaced)
volume = base area × height measuring cylinder
measuring cylinder
(final-initial volume of water)
