g by Free Fall Apparatus - Frederiksen [80909]

For precisely determining the acceleration of gravity - g. Very simple arrangement that students will immediately understand. The device consists of an electromagnet which releases the ball and at the same time starts the time measurement. When the ball reaches the impact plate, the time measurement will stop and you have very precisely measured the fall time of the ball, from the electromagnet to the impact plate. Using the relationship between h, t and g, g can be easily determined. Compatible with Student Timer (BEES Code 80908). Connection via 4mm banana connectors. Includes 4 gold-plated steel balls, two with a diameter of 12mm and two with a diameter of 16mm. Also included is a table tennis ball with the same mass as the steel ball with a diameter of 12mm. Stand not included.
