: To reduce human error, it is standard to measure the time for 10 or 20 oscillations and then divide by that number to find the time for one single period.

: Increasing the length increases the period. Specifically, if you quadruple the length, you double the period. 3. Step-by-Step Data Analysis Most labs require you to solve for or predict a specific length.

The period ( ) of a simple pendulum is determined by the length of the string ( ) and the acceleration due to gravity (
