Fundamentals of Physics Photogate System

Versatile System Expands Uses of All FUNdamentals of Physics Products.

This innovative photogate system is designed specifically for use with the entire Fundamental of Physics collection. Its unique design can be used for any motion based experiment, and easily attaches to any of the Fundamentals of Physics products. Battery operated, it allows you to conveniently perform experiments without being tethered to an outlet. There are four timing modes, including Gate, which measures the time of interruption; Pulse, which measures the time between interruptions; and Pendulum, which measures the time between the first and third interruption. Includes 9V battery and instructions.
