What Is the Uncertainty of a Meter Stick
If they all agree within one millimeter this also happens to be the smallest division we can view this one-millimeter as the uncertainty with which our meter stick would agree when compared. A common rule of thumb is to take one-half the unit of the last decimal place in a measurement to obtain the uncertainty. 1 2 Uncertainty And The Ruler Youtube One end of a uniform meter stick is placed against a vertical wall. . So meter stick uses 1m and 100cm. A common rule of thumb is to take one-half the unit of the last decimal place in a measurement to obtain the uncertainty. Therefore the instrument uncertainty for the meter stick is 01 cm. To get more precision you need a more precise more expensive and usually more. With a meter stick implies an uncertainty of 005 cm. Since you can calculate the relative uncertainty of M2. A You ALWAYS get 4 significant figures b You ALWAYS get 3 significant figures c The unc...
