A "g by free fall app" likely refers to an application designed to measure or calculate the acceleration due to gravity (denoted as "g") by using the concept of free fall. These apps typically utilize the sensors in smartphones (like the accelerometer) to detect the device’s motion during free fall, which can then be used to estimate the value of gravitational acceleration.
In physics, "g" represents the acceleration of an object in free fall near Earth's surface, which is approximately 9.8 m/s². A free fall experiment involves dropping an object and measuring the time it takes to fall a certain distance, from which "g" can be calculated.
