 You suspend various weights from the string and measure the displacement of the glider from its equilibrium position define as the position when a 100 gram weight is suspended initially. You suspend various weights from the string and measure the displacement of the glider from its equilibrium position define as the position when a 100 gram weight is suspended initially.
  
-Attach a piece of string to the glider and lay it on the pulley with a mass m of 100g suspended from the free end of the string as shown above. Record the position of your glider for the 100g weight and define this as your equilibrium position. Be sure that the string moves freely and does not scrape. Repeat with 4 other masses of 20g each for a total of four measurements. Make sure you are taking the difference between your position readings and the equilibrium position as your data. Enter the values for the additional mass +Before you start ensure your air track is level. ​Attach a piece of string to the glider and lay it on the pulley with a mass m of 100g suspended from the free end of the string as shown above.
