“G” BY FREE FALL APPARATUS ADVANCED

The “G” by Free Fall Apparatus – Advanced is designed for accurate determination of the acceleration due to gravity using the free-fall method. The apparatus incorporates an electromagnetic solenoid release unit that holds and promptly releases a metal sphere when the power to the electromagnet is switched off.

A gate switch unit is positioned below the release mechanism. It consists of a hinged steel plate held against an adjustable electrical contact by a small magnet. When the falling sphere strikes the plate, it moves immediately and operates the contact, providing a precise stopping signal to the electronic timer.

Both the solenoid unit and gate switch unit are mounted on adjustable plastic supports that can be securely clamped to a 12 mm diameter retort stand rod, allowing convenient adjustment of the falling height. The system is supplied with metal spheres, retort stand and a digital timer for recording the time of fall and calculating the value of g.
