→‎Improving Precision

: Ensure the glider remains motionless when no [[weight]] is attached. If the glider moves then adjust the feet on the air track until the glider remains stationary.

: [[Lubricate]] the [[pulley]] to reduce the [[force]] of [[friction]] which acts against the [[weight]] added.

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

~~: Use a ruler with a higher [[resolution]] to give a more [[precise]] [[displacement]] for the glider.~~
