Objective

• Measure the period of a pendulum as a function of amplitude

• Measure the period of a pendulum as a function of length

• Measure the period of a pendulum as a function of bob mass

Materials

• Power Macintosh or Windows PC

• LabPro or Universal Lab Interface

• Logger Pro

• Vernier Photogate

• Protractor

Procedure

• Take a 1 m long string tie it up to the stand on the table.

• Attach a Photogate underneath the string, so that when you attach the mass weight it will pass freely through the Photogate.

• Part I, amplitude test, change the angle three times, and see how it affects the period.

• Part II, length, change the length three times, and monitor how it affects the period.

• Part III, attach three different mass weights and observe the period will it change, record the data each time.

Results

• Discover that the period is only relation to the length of the string.

• Find out that T^2 is proportional to L.
