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.

4. Pendulum Lab /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.

Hypothesis: If I (increase/decrease) the length of the pendulum, then the time period will (increase/decrease, _________), because ________.
Variables:
Independent: Length of the pendulum
Dependent: Time period
Procedure: Adjust the length of the pendulum to 35 cm. Put 3 weights on the pendulum. Pull the pendulum back 50 ˚. Measure the time period the pendulum takes to complete 5 swings. Repeat a total of 5 times. Repeat using lengths 45 cm and 55 cm.
