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. Learn physics visually and interactively while having fun with the Free Fall Calculator! Thank you for your support, and feel free to visit nitrio.com for more apps for your iOS devices.
