Dropping the ball: Acceleration of gravity
Laboratory 032 involves timing the fall of a ball to determine the acceleration of gravity g.
Cecelia drops the ball while Brigida observes.
Eliander is the dropper-timer while Steward secures the meter sticks.
Mayleen and Irene work along the laboratory windows.
Nick and Kesusa work on top of a table to get drops as high as 300 cm. The final drops are made from a balcony outside that provide drop heights of 400 and 500 centimeters.
