Depending on the experiment, the recording of measured time may be to the nearest 0.1 s or the nearest 1 s, even though a typical digital stopwatch has a precision of 0.01 s. This is to account for uncertainty due to human reaction time or due to the time taken for observing whether an event has indeed occurred. In general, unless otherwise stated in the instructions, the measured time can be to the nearest 0.01 s or 0.1 s.

In this post, we will be going to the basics of setting up the retort stand and pendulum experiment. Most probably, this will be the first experiment which you will perform in the lab. Let’s start with the setting up the retort stand, boss and the clamp. Next we will take a look at how you set the up the apparatus for the pendulum experiment.
