====Improving [[Precision]]====
: Calculate the [[weight]] added 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]].
: Use a ruler with a higher [[resolution]] to give a more [[precise]] [[displacement]] for the glider. ===Experiment 2: Trolley with Markings=======Variables====: [[Independent Variable]]: The [[force]] applied to the [[object]].: [[Dependent Variable]]: The [[acceleration]] of the [[object]].: [[Control Variable]]s: The [[mass]] of the [[object]]. ====Method===={| class="wikitable"|-|[[File:RequiredPracticalFMA3.png|center|600px]]|-| style="height:20px; width:200px; text-align:center;" |A [[diagram]] of the [[apparatus]] used to investigate the effect of a [[force]] on the [[acceleration]] of an [[object]].|} : Set up the equipment as shown in the [[diagram]].#Adjust the [[gradient]] of the slope so that once pushed the trolley will move with a constant [[velocity]].#Attach a known [[weight]] (approximately 0.1N) to wire.#Release the [[weight]] and start the [[stopwatch]] allowing the trolley to [[accelerate]].#Record the [[time]] on the [[stopwatch]] at each 10cm marker.#Calculate the [[time]] difference between each 10cm marker.#Use the equation <math>v=s/t</math> to calculate the [[Mean Average|average]] [[velocity]] between each 10cm marker.#Use the equation <math>a=\frac{v-u}{t}</math> to calculate the [[acceleration]] of the trolley.#Repeat steps 2-7 adding 0.1N [[weight]] up to around 0.6N.#Plot a [[graph]] with the [[force]] of [[weight]] on the [[x-axis]] and the [[acceleration]] on the [[y-axis]].
