Simple Pendulum Lab:

Procedure
__**Part 1: Changing Mass**__ 1. Hang a string of approximately 1m from the board so that it can swing freely. 2. Attach a 50g mass to the bottom of the string 3. Move the pendulum to 45 degrees from the point of equilibrium. 4. Record the time it takes for the pendulum to complete 3 cycles. 5. Repeat measurements three times for accuracy. 6. Use the average to calculate the approximate period of the pendulum. 7. Repeat steps 3-6, adding 20g for each of the 5 trials.

__**Part 2: Changing Amplitude**__ 1. Hang a string of approximately 1m from the board so that it can swing freely. 2. Attach a 150g mass to the bottom of the string. 3. Move the pendulum to amplitude of 3.14/2° from the point of equilibrium and release it. 4. Record the time it takes the pendulum to complete 3 cycles. 5. Repeat measurments 3 times for accuracy. 6. Use the average to calculate the approximate period of the pendulum. 7. Repeat steps 3-6, using the amplitudes 3.14/6, 3.14/4, and 3.14/3.

__**Part 3: Changing String Length**__ 1.Hang a string of approximately 1m from the board so that it can swing freely 2. Attach a 150g mass to the bottom of the string. 3. Move the pendulum to an amplitude of 45 degrees from equilibrium. 4. Record the time it takes the pendulum to complete 3 cycles. 5. Repeat 3 times for accuracy. 6. Use the average to calculate the approximate period of the pendulum. 7. Repeat steps 3-6 using 1m, .75m, .5m, and .25m for the length of the string.

Data Collected:


The graph shows that the period of a pendulum is independent of it's amplitude.



The graph shows that the period of a pendulum is independent of it's mass.



The graph shows that the period of a pendulum changes as length changes. The longer the pendulum length, the longer the period.

__**Analysis:**__
The first two graphs show that changing the mass or amplitude of a pendulum does not have an effect on its period. Despite theses changes the period remained relatively constant.
