Ultrasound Physics Abstract: We looked at the mass-spring system and determined the spring constant by two different methods. We took measurements of T at 25 oscillations at 6 different masses. We graphed X vs. Mass (added) in grams. We determined the spring constant by using the formula K=1/slope x 9.8m/s. The graph was in agreement with Hooke’s Law because it was a straight line. We then squared T and graphed T vs. Mass (added) …showed first 75 words of 425 total…

…showed last 75 words of 425 total…Hooke’s Law. We also found the spring constant by the dynamic method, where at 6 different added masses were displaced from equilibrium position at 25 oscillations. We graphed T vs. the masses (added) in grams and found the spring constant using 4II/K=Slope. This graph was also a staight line which is in agreement with Hooke’s Law. We also found the mass effective by using the equation 4II/K (Ma) + 4II/K [(Ma) + (Meff.)]
