Answer:
he calculator uses the standard formula from Newtonian physics to figure out how long before the falling object goes splat:
The force of gravity, g = 9.8 m/s2 ...
Time to splat: sqrt ( 2 * height / 9.8 ) ...
Velocity at splat time: sqrt( 2 * g * height ) ...
Energy at splat time: 1/2 * mass * velocity2 = mass * g * height.
