The document describes two methods for determining the acceleration due to gravity, g, which is approximately 9.8 m/s^2. Method 1 involves measuring an object's weight using a newton meter or spring balance and its mass using a balance, but is not very accurate. Method 2 involves measuring the time of an object's oscillations using a stopwatch as it swings from a known height measured with a ruler, then using the period to calculate g based on the mathematical relationship between oscillation parameters and acceleration. The document notes potential sources of error in readings.
