A digital timer for a "g by free fall" experiment is a specialized electronic device that precisely measures the time it takes for an object to fall under gravity. It works by starting the timer when a ball is released from a release unit (often an electromagnet) and stopping it when the ball hits an impact plate at the base, which contains a vibration sensor. These timers are used in physics labs to demonstrate and calculate the acceleration due to gravity (\(g\)) by using the formula \(g=2s/t^{2}\), where \(s\) is the distance fallen and \(t\) is the time measured.
