Physics Oscillations

Done by: Priscilla, Sandy, Jing Han, Charissa, Qian Ning

Experimental outline
Aim: If the degree of release will affect the period of a pendulum swing.

Independent Variable: The different degrees. 10, 20, 30, 40, 50, 60, 70, 80 and 90 degrees.

Dependent Variable: The time for the pendulum swing to stop moving and the number of oscillations.

Procedure:
Step 1: Set up the pendulum swing and measure 10 degrees downwards from the stand.
Step 2: Release the pendulum.
Step 3: Record the number of oscillations and the time for it to come to a complete stop.
Step 4: Repeat steps 1-3 for 2 more times to calculate the average.
Step 5: Repeat steps 1-4 for 20, 30, 40, 50, 60, 70, 80 and 90 degrees respectively and record your findings.
Step 6: Compare your findings. Plot a chart and graph to better illustrate your findings.

How to find your results:
Take average time for the pendulum swing to stop moving divided by the average number of oscillations.
