PENDULUM INVESTIGATION

Aim of the investigation

The aim of the pendulum investigation is to see what will happen if I change a variable whilst I swing a pendulum and see the effect which it has on the pendulums time to complete one whole swing (from where it starts, to the opposite end, and back again). This will give me an insight into what will effect the time of the swinging of the pendulum, be it weight, string length, the angle, or the swinging point.

Planning my investigation

I will set up my investigation by having a 30cm length of string. This will be cut six times as I am measuring six different lengths of string. These will include lengths of: 30, 25, 20, 15, 10 and 5 centimeters. To make my results reliable I will test them three times each, at all the lengths, and average them out, to give a more accurate measurement. I think that I can produce reliable, precise results, using this information and plan. I will have enough data to spot “misfit” results too.

Safety Issues

For safety, I will use a pair of safety
