Free fall means that an object is falling freely with no forces acting upon it except gravity, a defined constant, g = -9.8 m/s². The distance the object falls, or height h, is 1/2 gravity times the square of the time falling. Velocity is defined as gravity times time. Free fall speed: When an object is released to fall down under the influence of gravitational force with no initial velocity, the velocity of a falling object is given by: v = g * t where t stands for time, g for gravity, and v for velocity. Free fall equation: The equation for distance or height fallen is given by: s = 0.5 * g * t² where t stands for time, g for gravity, and s for distance/height. Whether explicitly stated or not, the value of the acceleration in the kinematic equations is -9.8 m/s² for any freely falling object. If an object is merely dropped (as opposed to being thrown) from an elevated height, then the initial velocity of the object is 0 m/s.
