: 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. 4π2gthe fraction with numerator 4 pi squared and
: Does not affect the period. If you double the mass, the period stays the same. Amplitude (Angle) : For small angles (usually less than 15∘15 raised to the composed with power ), the angle does not significantly affect the period. If you double the mass, the period stays the same
