FREE FALL APPARATUS WITH DIGITAL
COUNTER
Introduction
Free fall apparatus with digital counter has been designed to calculate the
value of acceleration due to gravity. The digital counter device can be also
used as a stopwatch.
The free fall apparatus consists of an electromagnet mounted in a plastic
case to hold/release a metallic ball. As soon as the ball gets released from
the electromagnet, the timer starts counting; when the ball hits the
platform with an incorporated impact sensor, the timer stops. The time
taken by the sphere from top to bottom will be displayed on the LED
display of digital counter to calculate the acceleration due to gravity.
