Pendulum and Spring - Lab Report Example

The motion moves up and down between two extremes. The maximum displacement is called the amplitude. When a spring is hanging vertically with no mass, it has a given length. When the mass was added the length changed. Every spring also has a spring constant. The periodic time also reduces as the as the length of the rod of the pendulum was reduced. This exactly shows how the length of the rod varies directly with periodic time. The periodic time also reduces as the mass was being added on the rod.

There were some errors that occurred when carrying out the experiment, this lead to the inaccuracy of the various values and graphs drawn. The pendulum may not have been mounted in the same position as the gravity; it may not be pointing directly to the center of the earth. The pendulum surface may also not be aero-dynamic to avoid lift and drag by air. Mistakes could also be from measuring the length of the pendulum causing inaccurate
