I.Purpose The validity of the two systems, which is a spring-and-mass system and a simple pendulum, will be tested in this experiment. II.Equipments List ·Spring ·Different weights ·stopwatch (#001073) ·long ruler or meter stick ·wooden ball attached with a light string ·protractor (#001313) ·standing ·gradienter (#000925) III.Procedures Spring-Mass Sysyem (Static Method)1.Set up the stand/equipments 2.Hang the spring to the stand 3.Place a weight to the end of the spring and let it stretch to the intitial postion 4.Add a second weight and let the spring stretch to the final postion 5.Use a ruler to measure the the distance that is stretch by the added weight 6.Remove the second weight and add a another weight 7.Repeat step 5 and 6 with different weight to get 10 trials Spring-Mass System (Dynamic Method)1.Use the same set up as in the Static Method 2.Attach a weight to the end of the string 3.Pull the weight down by a little bit and release to make it oscillate vertically 4.Start the timer and stop after it oscillates 10 times 5.Remove the weight and add a different weight, then repeat 10 times with 10 different masses
Simple Pendulum1.Hang the wood ball on the stand. 2.Secure the long ruler on the stand. 3.Use the ruler to measure the distance between one end of the string to the center of the bal, and record the datal.
