Abstract

The most common way to find gravitational acceleration, g, in a laboratory is to use a simple pendulum and a clock. Alternately, g can be calculated by measuring time and distance for a free fall. Since the time of free fall in a laboratory is short, there are challenges in measuring the short period. In this article, a low cost technique to measure the time for a free fall using a discharging RC circuit is discussed.
