Free fall calculator finds the initial position, final position, initial
velocity, final velocity, maximum height, and time parameters of free fall in physics without air resistance.
Moreover, height (or vertical position) vs. time and velocity vs. time plots are drawn for the free falling object.
The free fall formulas used for calculations are given below.
