Paper 3 Flashcards
where should a fiducial marker be placed and why?
at the equilibrium position, where the transition time is smallest as its moving fastest here
How would you measure amplitude of a pendulum?
use a set square and measure the horizontal distance between the maximum position and the equilibrium. measure from one edge not the centre
how to calculate percentage change?
change/ original x100
how can you tell if a result is an anomaly?
if it significantly affects the range
How would you draw a graph
label axis, fill whole page
how do you measure using a vernier calliper
measure distance from 0 then see which value after 0 lines up the best
what is a type of error that is sometimes different
random error
what time of error is consistent
systematic error
what happens after an objects elastic limit is exceeded?
it undergoes plastic deformation
what are some common issues with experiments?
safety hazard, more uncertainty, smaller range of values
what is a parallax error
not reading measurements at eye level
