EXPERIMENT LINEAR AIR TRACK
1)In the experiment to investigate Newton's second lawof motion by using linear air track,explain the function of eachapparatus used,which are air track rail,blower,pressuretubr,gliders,flag,photogate,string and pulley.
2)Why do we need to measure the length of the flag toget the accelerationnand why do we use the formula a=2X/t2?.
3)Is there any friction force involves and suggest theways to improve this experiment
