Practical investigation on teminal velocity of a sphere in oil

Physics CAT One Extended Practical investigation Report Student Number: Purpose         The Purpose of this analyse is to explore how the terminal velocity of a field of force become through glycerine varies with the temperature of the glycerol and the size of the force field. Introduction         In the early stages of the check it was intended to investigate how the speed of a sphere perishing through glycerol varies with the size of the sphere. However, after digest it was refractory that the investigation would be more callenging if a bite variable was incorporated. There ar many constants that could have been manipulated much(prenominal) as, make out of glycerol used, distacnce over which times were taken, duration sphere was allowed to fall before timing was taken and the temperature of the glycerol. aft(prenominal) much quotation it was decided that the temperature of the glycerol should be varied. erst this had benn incorporated into the investigation some scientific concepts related to the viscousness of a smooth-spoken had to be attained. (Refer to article).         In conducting the experiments an attempt was make to attain results that could, let graphs that showed the terminal velocity of a sphere related to the temperature of the glycerol and the terminal velocity of a sphere related to its size. Apparatus used *         600 ml of glycerol (density 1.26/ml. study 98.0 - 101.0%) *         Small ball bearings of radius:         3.175mm                                                      3.960mm                                                      5.

000mm                                                      6.000mm                                                      7.000mm *         900 ml measuring piston chamber *         Stop watch *         Thermometer *         Some type of heating and dispassionate device to varie the temperature of the glycerol *         Tweezers Variables and Constants         The variables that have been used in this investigation are the size of the ball bearings and the temperature...
