====Improving [[Precision]]====

: Calculate the [[weight]] correct to two [[Significant Figure|significant figures]] by [[measure|measuring]] its [[mass]] to two [[Significant Figures|significant figures]] each time and using the equation <math>W=mg</math> with <math>g=9.8</math>. This will give a more [[precise]] knowledge of the [[weight]] rather than relying on the number printed on the [[weight]]s which may be [[precise]] to only one [[Significant Figure|significant figure]].

: Add a [[Fiduciary Marker|fiduciary marker]] with a fine point to the bottom of the [[Coil Spring|coil spring]] to give a [[precise]] [[read]]ing of the length of the [[Coil Spring|coil spring]].
