Affordable spark timer for your physics lab.
This apparatus is used for determining the rate of acceleration in a falling weight, calculating the speed of a moving art or studying the forces of friction.
A paper tape is pulled through the timer while a spark at precise and same interval is created which burns tiny dots in the paper strip. The faster the strip passes through the timer the larger the distance between the dots. This allows you to calculate the acceleration.
