what is the equation for a period of a pendulum
The equation for the period of a simple pendulum starting at a small angle (a) is: T = 2pi*SQRT(L/g). or. T = 2Ïâ(L/g). where. 1  T is the period in seconds (s). 2  pi = 3.14 (it is also written as the Greek letter Ï).quations for period and frequency. The period of the motion for a pendulum is how long it takes to swing back-and-forth, measured in seconds. Period is designated as T. The frequency of a pendulum is how many back-and-forth swings there are in a second, measured in hertz. Frequency is usually designated as f.
