PURPOSE: To quantitatively demonstrate how the spring constant effects the period of a mass on a spring.
DESCRIPTION: Determine the spring constant from the relationship F=kx using various numbers of 200 gram weights hanging from the spring. Hang groups of 200 gram weights from the spring and create vertical oscillations, obtaining the period usin g the manual timer. Compare with the period calculated from the relation T = 2 pi SQRT (m/k), where k was obtained above.
This can be compared with actual integration of the equations of motion using a computer.
