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