Establish the dependence of the period of oscillation of a spring pendulum on the stiffness of the spring.

Hypothesis: The greater the stiffness of the spring, the shorter the period of oscillation of the spring pendulum.
The order of work: 1. Suspend loads of equal weight on springs of different stiffness
Measurements # – k? N / m – n – t ± Δt, s – T ± Δt, s
1 – 4 – 20 – 8 – 1.256
2 – 16 – 20 – 12 – 0.628
Conclusion: The greater the stiffness of the spring of a spring pendulum, the shorter the period of its oscillations
