Summary Physics Practical Skills (Errors and Uncertainties)

Types of errors uncertainties



error content data always the same
systematic error
error Zero
Random error error not constant reaction time
error at thesame not thesameeverytime


randan error always occur l
Systematic error does
not introduce anydifference between theactualvalue
when thegradient
of thegraph remainsthesame
there is systematic error

like confine the range

and restrict it to only within the range
