1C10.05 - Ultrasonic Detector & Student - Car

Code Number:
Demo Title:
Ultrasonic Detector & Student - Car
Acceleration and Velocity
Area of Study:
Interface with Motion Sensor, Computer, and Student, Car or Ball.

Have a student stand in front of the motion sensor and move towards or away from the motion sensor to make the position, velocity, or acceleration graphs desired.

A car or a ball may be used instead of a student.
