Experiment Equipment of Newton's Second Law Based on Photoelectric Sensor
Using photoelectric sensor collects two physical quantities, displacement and time of the experiment car. The signal realizes conditioning after amplifier-filter circuit. It is transferred to computer through the serial portion of RS-232 after the disposing of Single-chip Computer. The experiment software designed by ourselves calculates size and relationship between the physical quantities relevant to acceleration, and draws the relevant figures of the physical quantities.
