摘要：
This paper shows how a simple and familiar circuit can be used to make a photogate timing system. The cost of the system is very low and the results are quite satisfactory. The experimental results for a small car rolling down a straight track were compared with analytical predictions and it was shown that aerodynamic drag was negligible.
