This is what we did in this lesson.
Aim:To determine the relationship between the period and the length of the simple pendulum.
Apparatus:100cm thread, pendulum bob, metre rule, split cork, stopwatch, clamps, retort stand
Procedule:
1)Adjust the length of the pendulum to 15.0cm
2)Give the pendulum bob a small displacement,10 degrees, and set it into oscillation.
3)Count the number of complete oscillations in a 30 second interval.
4)Record the number of full swings in column 2 of the table below.
5)Repeat the procedure for 25.0cm, 35.0cm, and 45.0cm.
This video is an example of what we did.
Interesting,don't you think?
