The error is reduced if the calibration ruler section and the plane where the steel ball moves are on nearly the same plane. If 'a' represents the distance between the calibration ruler section and the camera, and 'b' represents the distance between the plane where the steel ball moves and the camera, the correction is obtained by multiplying the measured value of gravitational acceleration by b/a. #Tracker #FreeFall #PhysicsExperiment #Gravity #GravitationalAcceleration
