Designed to determine the rate of acceleration of a falling weight, calculate the speed of a moving cart, or study the forces of friction. Paper tape is pulled through the timer while a spark at a very precise interval is created which burns tiny dots in the paper strip as it passes. The distance between the dots determines how fast the object is falling or moving. Makes a formula a more visual concept to comprehend.
