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.
