Mechanics: Persistence of Motion

PIRA Class: 1F30.10

Purpose:
To observe the persistence of an object in a motion that is relatively free of external forces

Description:
An object in motion (cart on an air track) will continue in the same state of motion unless acted upon by an external, unbalance force (air resistance, end of track bumpers).

1. Set up air track up w/ rubber band bumpers at ends; attach air supply.

2. Check level of air track and shim if necessary

3. Place cart on air track and give it its initial motion. (To increase the duration of the run, add equal masses to each side of cart)

Equipment:
Air track, air track accessories, air supply

Location:
Shelves 117 (air track), 112 (glider & masses), 521 (air pump)
