Page 16 Pendulum Lab 8/29 Question: What affects the time period of a pendulum? Notes: Pendulum is an object connected to a fix support in such a way that it is free to swing back and forth under the influence of gravity. Time Period is an amount of time. Time Period of a Pendulum is an amount of time an object requires to make one complete swing.

Pendulum Lab 8/29 Brainstorm with Your Team What can you change about a pendulum that may have a possible effect on the time period of a pendulum.

Pendulum Lab 8/29 Variables: Independent: Weights 16/18 Pendulum Lab 8/29 Variables: Independent: Weights Dependent: Time period Procedure: Place one weight on the pendulum. Adjust the length of the pendulum to 30 cm. Pull the pendulum back 25˚. Measure the time period the pendulum takes to complete 5 swings. Repeat a total of 5 times. Repeat using 3 and 6 weights.
