Pendulum Experiment Outline

Done by: Jun Yang, Benjamin, Shi Heng, Han Kang

Goal of Experiment:

To find out if the length of the string of the pendulum affects the period of one entire oscillation.

Procedure:

1. Take down the time taken for a complete oscillation using the 10cm string when dropping the pendulum from a 45 degrees angle.

2. Repeat step 1 but replace the 10cm string with a 15cm string.

3. Repeat step 1 but replace the 15cm string with a 20cm string.

4. Repeat step 1 but replace the 20cm string with a 25cm string.

5. Repeat step 1 but replace the 25cm string with a 30cm string.

6. Repeat step 1 but replace the 30cm string with a 35cm string.

7. Repeat the experiment 2 more times and take down the average.

Materials:

-35cm string

-30cm string

-25cm string

-20cm string

-15cm string

-10cm string

-Pendulum

-Retort stand

-Stopwatch

Hypothesis:

Period of oscillation increases as length of string increases.

Table to record data:

What this graph shows:

Period increases as length of string increases

Other possible scenario

Scenario 2

What this graph shows:

Period is not affected by length of string.

Equation of graph: T=C

Scenario 3

What this graph shows:

Period decreases as length of string increases.

Equation: T=m(l)+C

Scenario 4

What this graph shows:

Period of oscillation increases when length of string remains the same.

Equation: T=∞
