Abigail Hundt 11/02/17 Imani Walt & Kaitlyn Groves Simple Harmonic Motion Summary The objective of this experiment was to explore Hooke’s Law and evaluate the period of motion as functions of amplitude and mass. After experimentation, the spring constant was determined statically and dynamically for accuracy. Body Estimates of position, velocity, and acceleration for a mass on a spring Measurements of amplitude and period: Y max: 0.225 m -Y max: 0.122 m Mass: .250 kg T= 2π m g T=2 π 0.250 kg 9.8 m / s 2 T=2 π (0.1597) seconds

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
