How do you measure height by dropping an object?

Answer 1

-- Take a heavy object and a stopwatch.

-- Start the timer as you drop the object from the unknown height.

-- Stop the timer when the object hits the ground.

-- Read the time off the watch, in seconds. Square it. (Multiply it by itself.)

-- Multiply that result by 16.1 .

-- Now you have the distance the object fell, in feet.
