## 5.1 Determine the period of a simple pendulum with a length of 49.0 cm.

.

### Start the pendulum swinging with a very small displacement. The smaller the arc the more accurate the relationship.

• One swing is one complete cycle, back and forth.
• Let it swing a few times before starting the count.
• Enter the data in the table below.
• Divide the time for ten swings by ten to find the period.
