Object: To study the simple harmonic motion of a spring mass system. To find the spring constant, and compare it to Hooke’s Law Procedure: To start, set up the experiment as shown in the free hand diagram of the experiment. First, weigh the mass of the spring. Now find its elongation while it is unloaded. Next, add a weight and measure the new distance of the spring. Subtract the new elongation from the original elongation and use that value to find the coefficient of the spring using this equation: k = (m * g) / x Repeat this ten times incrementing the amount of mass put on the end of the spring. For the following part, part two, take the same weights used before and do the following: add the weight to the spring, stretch the spring; let go and take the time it takes to go 25 cycles. Like in the first part, repeat this 10 times increment the weight for each trial. Sample Calc: mass of spring = Initial elongation of spring = .253 (m) gravity = 9.8 (m/s) For trial # 1 K static = (m*g)/x
