Code Number: 1C10.05

Demo Title: Ultrasonic Detector & Student - Car

Condition: Excellent

Area of Study: Mechanics

Equipment: 

Interface with motion sensor, computer, and student, car, or ball.

Procedure: 

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.  Holding a square of Plexiglas or other flat reflector against your chest will give a smoother graph.

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