As we mentioned in Chapter 10, engineers used to use pendulums to measure the value of g at a location. The formula used to measure the acceleration due to gravity is

where g is acceleration due to gravity (m/s²), L is the length of pendulum, and T is the period of oscillation of the pendulum (the time that it takes the pendulum to complete one cycle). For a pendulum of 2 m long, create a graph that could be used for locations between an altitude of 0 and 2000 m, and shows g as a function of T.
