1C10.25 - Air Track - Constant Velocity

Code Number:
1C10.25
Demo Title:
Air Track - Constant Velocity
Condition:
Good
Principle:
Constant Velocity
Area of Study:
Mechanics
Equipment:
Air Track with Cars.
Procedure:

Level the air track and using the desired car show a constant velocity.  The best way to do this is to start the car near one end of the air track.  Move the car towards the nearest bumper and after it hits the car should be moving at a constant velocity through out the length of the track.
