The IEC 'Free Fall' apparatus comes in several forms. This one is a 1m fall and uses a mechanical release for the ball and 3 balls of different sizes and materials are used. The upper platform is adjustable for position on the 1m vertical rail so that experiments can be performed at different falling distances. An electronic timer is connected to the upper and lower platforms to obtain a signal as the ball begins to fall and another when the ball hits the lower platform. In this model, the metallic ball itself creates the electrical connection for the 'start' signal and the plate at the bottom senses the ball striking it. By gently pulling a strong cord, the ball is held against the underside of the upper platform to make connection to the 'start' sockets. When the pin is pulled from the ball it falls to immediately start the timer and the bottom platform instantly stops the timer. The timer can be the LB4057-001 (LCD) or LB4064-101 (red LED) or any one of several others. All cables and plugs are supplied in the kit. IN THIS MODEL, THE TIMER IS NOT INCLUDED.
