4��2gthe fraction with numerator 4 pi squared and denominator g end-fraction : Rearranging the formula to find gravity:
: 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. pendulum lab worksheet answers
). Below are common answers for a standard pendulum lab worksheet. 1. The Core Equation The mathematical relationship for a simple pendulum is: 4��2gthe fraction with numerator 4 pi squared and
T=2��Lgcap T equals 2 pi the square root of the fraction with numerator cap L and denominator g end-fraction end-root : Period (the time for one full swing back and forth). Step-by-Step Data Analysis Most labs require you to
: 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.
: Does not affect the period. If you double the mass, the period stays the same. Amplitude (Angle) : For small angles (usually less than 15�닔15 raised to the composed with power ), the angle does not significantly affect the period.
