Components make up this heavy gauge aluminium and plastic air track.
It allows for experiments in kinematics and dynamics principles by creating a frictionless system. Since air has very low friction, an object glides along with practically constant velocity when there is no applied force.
The air track is built with a triangular section of light alloy with small holes at equal distance one from the other on the two faces. When a slide is put on the track, the air coming out of the holes reaches a sufficient pressure to lift the slide a fraction of a millimeter, so the friction is now negligible.
This track is fed with a low pressure compressor that provides a large quantity of air at a pressure slightly above the atmospheric. Setting up these dramatic presentations of mechanics is quick and simple. In minutes, students or instructors can set
up many different experiments.
The appparatus includes a 2.0 meter air track; two 400 gram gliders; one 200 gram glider; bumpers; rubber bands; elastic cords; pulley; electromagnet; metal pendulum bob; and various asseccories, such as string and clay.
Required, but not included are a blower (WLS1801-08 and WLS1801-09) and photogate system (WLS1800-93).
