GRAVITY ACCELERATION DEMONSTRATION: By Free-Fall Apparatus
For demonstrating gravity or ‘G’ by the free fall method. The apparatus comprises an electromagnet which is housed in a plastic case fitted with two 4mm sockets for connecting to it.
Another pair of 4 mm sockets are used to connect a suitable electronic timer for timing the fall. A ball-bearing (supplied) is held in place by the electromagnet.
When the electromagnet is switched off the ball-bearing falls and hits a platform which activates a micro switch stopping the timer.
The time of the fall is recorded on the timing device. Retort stand not included.
