Assumptions for the experiment

In this experiment, we assume that the spring is weight-less. Also, we assumed that the effect of air resistance acting on the mass and the spring is negligible

.

Difficulties encountered

  When conducting the experiment, we initially used a spring which cannot be extended significantly. As a result, we cannot conduct the experiment efficiently as we couldn’t see the tiny change in period. Later, we replaced it with another spring with greater extension so we could conduct the experiment more smoothly.

  We encountered difficulties in counting the number of oscillation because initially ...
