   - Level the air track by carefully adjusting the single leveling screw at one end of the track. ​ When the track is level, the glider should remain nearly stationary at any point on the track. ​ Be sure to tighten the wing nut on the leveling screw when the track is level.   - Level the air track by carefully adjusting the single leveling screw at one end of the track. ​ When the track is level, the glider should remain nearly stationary at any point on the track. ​ Be sure to tighten the wing nut on the leveling screw when the track is level.
   -Attach a 20 gram mass (NOT more than 20 g!), to the glider with a piece of string and rest the string on the pulley at the end of the air track so that the mass hangs over the edge of the table and can fall freely. ​ Record the value of this mass and an assumed error of 0.2 grams on your worksheet. Make sure the string with the weight attached is long enough so that you can reach the far end from the pulley and can start the motion with the photo gate in front of the first “picket”. The string should not be too long. The weight should not hit the ground before the glider is ~ 10 pickets from the end on the pulley side.   -Attach a 20 gram mass (NOT more than 20 g!), to the glider with a piece of string and rest the string on the pulley at the end of the air track so that the mass hangs over the edge of the table and can fall freely. ​ Record the value of this mass and an assumed error of 0.2 grams on your worksheet.
