Arbor Scientific Acceleration of Freefall Kit (PX-4421) The Probing is very importantIncludes materials needed to perform the Acceleration of Freefall Experiment as explained in Lab 31 of the Conceptual Physics Lab Manual. The adjustable burette clamp attaches directly to the ring stand (not included), so a right angle clamp is no longer necessary for the setup. The upper nail has been replaced by a screw eye to standardize the start position of the steel bob for more consistent hits. Best results will be obtained if the meter stick
