Results (3 points) : Static spring constant (ks) 30.5 ± 0.4 N / m Dynamic spring constant (kd) 28.6 ± 0.5 kg / T 2 Effective mass (m0) 0.006 ± 0.004 kg Discussion and Conclusion: The objectives of this lab were to verify the linear relationship between displacement and elastic force for different objects, measure the value of the dynamic spring constant, and measure the effective mass of the spring. In this lab, Hooke’s law and oscillation were studied. Springs are elastic and can exert or have force, but with different elasticity for each spring. Hooke’s law helps define the force of a spring, and can be simplified into an equation and is defined as F(x) = -k s (x-x 0 ) or, with x 0 set to 0, F(x) = -k d x. Therefore, the equation for the spring’s constant is N/m. Theoretically, the static spring constant and the dynamic spring constant of a single spring should be equal to each other. The spring constant is the value that determines or signifies how elastic the spring is.

### 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.
