- - If it dropped from a height of 0.5 foot, then it would reach the floor

in 0.177 sec. You could not measure the time accurately with a

stopwatch, because your own reaction time is the same order of

magnitude as the time you'd be trying to measure.

- - If it dropped from a height of 0.5 meter, then it would reach the floor

in 0.319 sec. You could not measure the time accurately with a

stopwatch, because your own reaction time is the same order of

magnitude as the time you'd be trying to measure.

- - If it dropped from a height of 0.5 kilometer, then ... ignoring air

resistance ... it would reach the floor in 10.1 sec. You could measure

that time quite accurately with a stopwatch.
