1C 10.27 - Velocity - Pasco Cars & Track

Demonstrates: Changes in velocity, momentum, collisions
Description: Car(s) on track and push. Add masses to change force needed to accelerate car. Uses motion detector to show real time graph of acceleration and/or collisons.

1C 20.10 - Free Fall in a Vacuum

Demonstrates: Objects falling at the same rate in a vacuum.
Description: Feather, penny, a piece of paper all fall at the same rate when the chamber is evacuated.

1C 20.30 - Air Track as an Inclined Plane

Demonstrates: Acceleration.
Description: One end of the large air track is elevated and a car accelerates. Motion detector shows via a real time graph change in acceleration.

1C 30.10 - Free Fall Apparatus

Demonstrates: Gravitational constant of Earth, g; acceleration due to Earth's gravitational pull.
Description: When the bearing is released a timer is activated and stops when the bearing has traveled 2 meters.

1C 30.26 - Timed Free Fall

Demonstrates: Acceleration in free fall.
Description: A series of weights are spaced so that when dropped they hit the floor at equal intervals.

1C 40.55 - Air Track Inch Worm

Demonstrates: Center of Mass.
Description: Two air cars are tied together with a spring and oscillate about the combined center of mass.
