1. Resonance of a spring
... that the weight of the mass is equivalent to the force exerted by the spring. Now that k and m are known, it is possible to calculate the spring's theoretical natural frequency. To determine the natural frequency experimentally, the mass is allowed to bounce for five periods while it is timed: Mass (kg) Äx (m) k (N/m) Time (sec) No. Of Osc. fN predicted (1/sec) ... ù to fN: At each different linear velocity, the amplitude of the spring-mass system is measured. Now, percent error can also be calculated between the experimental and the theoretical natural frequency. v (m/sec) Radi...
