Newton's Second Law

This experiment uses an AirTrack to confirm Newton’s second law that force = mass times the acceleration.  A pully arrangement is used to allow an adjustable weight to pull the glider along the AirTrack so that it accelerates.  By measuring the time the glider takes to pass through two successive photogate timers its acceleration can be calculated.  Changing the weight pulling the glider allows for a range of forces and accelerations to be observed.  These values can be plotted to confirm the law.
