What is the generally accepted value for gravity where the students conducted their experiment? In part a i we assumed the pendulum was a simple pendulum one with all the mass concentrated at a point connected to its pivot by a massless, inextensible string. If displacement from equilibrium is very small, then the pendulum of length $\ell$ approximate simple harmonic motion. Math Assignments Frequency of a pendulum calculator Formula : T = 2 L g .
