The Economy spark timer is ideal for determining the rate of acceleration in a falling weight, calculating the speed of a moving cart, or studying the forces of friction.
- Students calculate speed and acceleration
- 60 sparks per second (60 Hz)
- Items enclosed for safety
The measured object pulls a paper strip through the timer to generate a series of sparks at precise moments. The sparks burn tiny dots into the paper strip as it passes. The faster the strip passes through the timer, the larger the distance between the dots. Students then calculate the speed and acceleration of the object.
Everything on the spark timer is enclosed for safety.
Delivery information: This timer includes a roll of spark timer paper, a replacement electrode, a free-fall weight, and a cord and plug for 110 V operation.
