Classroom experiments using modern experimental tools like smartphones are in growing popularity. Hence, this study conducted a comparative experiment to determine the acceleration values due to gravitational force in free fall and projectile motions using simple materials and the sound sensor. In this experiment, the relationship between the height and the time squared of the fall in both free fall and projectile motions is represented in regression model. Notably, experimental values for g for free fall and projectile motions are close to the accepted acceleration value due to gravitational force. © 2024 IOP Publishing Ltd.
