The Free Fall Acceleration Formula and simply the free fall formula for bodies.

For the standard number of acceleration of gravity, the number denoted by the letter g should be taken.
And it is equal to g = 9.80665 m / s2 (meters per second squared)
The acceleration with which the body moves to the ground is called the acceleration of gravity.
formula
The standard formula is as follows.
g = G * (m3 / (R3) ^ 2)
Where G-gravitational component G = 6.67234 (14)
m3-Earth mass
R3 is the radius of the Earth.

Formula for all bodies without initial free fall velocity
V = V0 + gt
Where V is the final speed
V0 – initial speed (0 km / h)
g-acceleration of gravity
t-fall time.
