The period of the pendulum for student experiment.
1. Preparation
Teacher should prepare the pendulum apparatus and a stopwatch, and a ruler for this student
experiment.
2. Procedure
1) Set the thread length of pendulum about 20 cm by using the ruler.
2) Hook a weight (10g) on the string.
3) Lift the weight up to the angle of string θ (amplitude) = 8 ~ 10 degrees.
4) Measure the time by a stopwatch during 10 periods of back and forth motion.
5) Fill out result on the datasheet.
6) Change conditions of experiment, such as: add weights, change length of the string pendulum
(to 25, 30 cm etc.) and make the experiment again and again to see the different results.
3. Result
Length(cm) Weight(g) Total Time(s) Time/10(s)

*”Time/10” is “Total Time” divided by 10 (the amount of
periods).
The pendulum’s period is shown as below:
*T is period, L is length of pendulum, g is gravitational
acceleration. The equation is for teacher.
