A measurement of the difficulty of performing an aiming movement. It states that the difficulty of a movement is mostly correlated with the distance a limb moves and the narrowness of the target. 2. Distance had a little to no effect on movement time for my data. The size of the target had a huge impact on movement time. The

Geometrical Optics: Snell’s Law PHY101 Lab 12 Date: July 23rd‚ 2012 Objective: The purpose of this laboratory activity is to develop a set of experimental procedures that answer questions regarding Snell’s Law and the index of refraction. Ultimately‚ the experimental procedures you develop will allow the index of refraction to be found for water and cooking oil. 1. Explain how to experimentally determine the index of refraction of two substances. 2. Develop a set of experimental

Materials * Helical spring * support * rods * weight hanger * slotted masses * vertical scale * stopwatch. Procedure Part I: Determination of k from Hooke’s Law 1. Suspend the spring from its support. 2. Hook the weight hanger from the bottom loop of the spring and determine the vertical scale reading of the bottom of the weight hanger. 3. Record this as the equilibrium position of the system. 4. Add 5 g to the weight hanger and again record the actual

Determining the Concentration of a solution: Beer’s Law Objective In this lab of Determining the concentration of a unknown solution: Beers Law. We determined the concentration of a unknown CuSO4 solution by measuring its absorbance with the colorimeter. With all the calculations we were able to solve the linear regression Equation of absorbance vs. concentration and the alternate method.
